    This is great; thank you very much. However, when will the answers be posted (by Steve Sibol?)?

    how come ny state has released the chem curve so fast, yet this is taken for ever, it really killing me

    • Mike permalink

      You’re absolutely right, Paul.

      I thought that the curve was supposed to be a reflection of what students needed — it was supposed to come out after all the exams were graded, and be so made as to accomodate the majority of students.

      Yet, NYS put out the Chem conversion chart fifteen minutes after the end of the exam and the English part II chart while the exam was STILL in progress!!

      I don’t know WHAT’s going on with Trig, but I do know that a lot of students failed it, so the state is probably working hard to determine what percentage of students to accomodate: should the curve be 45, or 40, or 35?

      The state does not want EVERYONE to fail, but at the same time it doesn’t want to anger teachers with an especially low cut-off (like 30, which is what it did for Algebra in June 2008 — and which upset a lot of teachers b/c that’s just ridiculous).

      Another reason why this is taking so long is b/c this year marks the 1st administratiuon of the AlgII/Trig Regents: logically, it takes longer to come up with a conversion chart that the State never came up with before.

      I think that the cut-off will be around 40 because this exam was never given before, so the students did not have anything to study off of (no previous exams, no idea what exactly would be covered…).

      Good luck!

        my teacher said there would be a log equation, regression,completing the square, factor by goruping and none of that was on there.. my guess is that nys is seeing what an apporiate curve is so that most of the kids pass, or they enjoy messing with us

          First of all, no one knew what would be on the Regents exam b/c this was the 1st administration — the 1st of its kind.

          Regressions are purely calculator work.

          There was a log question, just in the mult. c., not the long-response.

          There are so many Qs that they can ask (34 or 37, I think it was).

          And, yes, a lot of people did terribly, so NYS is weighing its options.

          It is not the case that NYS is “messing with” you; the teachers are just as nervous.

          lET’S FACE IT: 1st test, it’s kind of hard to determine what the cut-off should be.

          Let’s just be patient and hope for the best.

          I’m 17 (just turned) and I took the “last” math b regents last June. It was incredibly easy, I got a 93 and I took just one practice test and did little additional study. I don’t consider myself an exceptional student at math at all, so I don’t see why so many kids are failing a regents thats suppose to be easier!! This is all so ridiculous, Teachers need to learn how to teach their kids, kids need to learn basic study habits. Also, I read that there were few questions with “Artificial information” or something. T_T if they cant understand “Artificial information” they must not have basic comprehension skills.

          No, Paul, I am not a math teacher — just a student who knows the system very, very well.

    • July 2, 2010 pm31 1:02 pm 1:02 pm

      I think the old system of just taking the Regents tests without any curves whatsoever were best. You didn’t have to wait so long to find out what you got and the scoring meant something. They’re not hard to pass, or do well in, for that matter. The only requirement is that the student studies the material.
      Now they give you the use of a graphing calculator, a whole reference sheet with formulas, and then curve the test. I think it’s pathetic how many kids get into high school without knowing enough basic math (such as fractions, multiplication and division, and order of operations). Then, because they don’t have a good grounding in math, they don’t do well in the upper classes of math and “need to” have a conversion chart put in place so that the students pass.

    for the question in the long response where it was sinx=sin2x
    the answers were: 0, 60, 180 and 300

    If i did guess and check and i only got one answer (60) do u think ill get any credit if so how much.

    • Mike permalink
      June 17, 2010 pm30 12:24 pm 12:24 pm

      If it was a 4-pt. Q and you showed your work, you would definietly get credit (1 or 2 pts.).

      (BTW, you mistyped the Q — it was 2sin(theta)cos(theta) = sin(theta); but I know exactly which one you are referring to.

      You won’t get all points (obviously), and depending on how much work you did, it’ll be 1 or 2 (3 isn’t likely, esp. b/c I don’t know what you mean by “guess and check”).

      • Noel permalink
        June 17, 2010 pm30 12:26 pm 12:26 pm

        He typed it correctly, it was sin(2 theta) = sin(theta), but you had to substitue using the identity to yield, 2 sin theta cos theta = sin theta. In any case, if he got only 1 solution out of 4, he will probably get 1/4 points.

        • Mike permalink
          June 17, 2010 pm30 12:31 pm 12:31 pm

          My fault, you’re right; he’s right.

          but i don’t agree about the pts.

          If you do all the substituting work, and jsut forget that you need ALL the values of x, do you really think that that is worth just a single point?

          Clearly, if you sub and get to 60 degrees, you know what you’re doing.

        • Noel permalink
          June 17, 2010 pm30 12:36 pm 12:36 pm

          I don’t know how plugging in random values, shows what you are doing. But based on what Porgey, said I think you should get 1/4, or at most 2/4, but high unlikely, so I’ll think of 25% credit for that question.

      • Porgey permalink
        June 17, 2010 pm30 12:32 pm 12:32 pm

        ill use x instead of theta since theres no theta key on my keyboard lol

        But you are incorrect the original question stated sin2x=sinx….once you looked at the reference table you could see that sin2x=2sinxcosx. Thus you can state that 2sinxcosx=sinx

        By the “guess and check method” i mean instead of solving it algebracially i just plugged in in values for “x” and since 60 worked i put it as my answer not knowing at the time that there were 3 other values that could have worked
        According to the the speaker you could use the guess and check method as long as you took 3 guesses.
        This is why im wondering if ill get credit for work and since i had 1/4 of the total answer im trying to figure out if I will at the least get one point

        • Mike permalink
          June 17, 2010 pm30 12:38 pm 12:38 pm

          My fault, you did type everything correctly.

          Guess and check does not mean that you check only the right answer and it works.

          You have to do it three separate times (and make it not work 2 of those times).

          So if you did that, I think that you will definietly get 2 or 3 pts.

          Why couldn’t you solve it the normal way, though?

          Good luck! We’re all praying for a low cut-off score (well, except for Noel, who probably got a 100 and doesn’t even need to see the chart…).

        I based the m/c off what I put on my answer sheet, and the ones I didn’t remember, I worked out myself. The short answer I got from another post on this blog “Last minute tips”, and I got all these answers for short answers, and know how to get them, so I’m sure they all right for short answers. The m/c I think are all right, however I might have made an error or two transferring.

          First of all, call up the school to see if you can get your raw score (or get your parents to do it).

          Second of all, Brooklyn Studio put the raw scores (see nylearns.org/pcuoccio if you want to see how many people flunked).

      • Anon. permalink

        You’re correct, however the correlation coefficient cannot be lower than -1 or higher than 1, making -.89 the correct answer. (I’m assuming you chose -1.07?)

    • Noel permalink
      June 17, 2010 pm30 12:44 pm 12:44 pm

      1 – 27 = 2 points each
      28-35 = 2 points each
      36-38 = 4 points each
      39 = 6 points

      Add them up: 2(27) + 2(8) + 4(3) + 6 = 88
      Which is maximum 88 raw score.

        June 17, 2010 pm30 1:05 pm 1:05 pm

        She asked for Raw score 70 equaling what % of a grade, not the other way around. And besides, she can’t even know her % grade because a conversation chart isn’t even out yet.

    for #7, does order matter when placing the cameras into box a?

    • Noel permalink
      June 17, 2010 pm30 1:02 pm 1:02 pm

      Number 7 I wasn’t sure actually between 20 C 3 or 20 P 3, however I don’t think order matters, so it’s 20 C 3. (Choice 3) I later asked a couple of my friends, and they proved to me both through just thinking about it, to mathematical formula why it’s a combination. So the answer is (3) and order doesn’t matter.

      • Anonymous permalink
        June 19, 2010 pm30 8:33 pm 8:33 pm

        Its 20 C 3 because even if you put camera 1, then 2, then 3 in a box, its the same grouping of cameras as if you put camera 2, then 3, then 1 in that box, so order doesn’t matter.

    Should we go up to New York State and demand the conversion chart.

      June 17, 2010 pm30 3:53 pm 3:53 pm

      Given how poorly everyone did (well, not everyoen but this IS aMERICA where we talk about the majority), I think it is best to get on the good side of the board of regents.

      Be patient; they’re trying to figure out just how low the cut-off should go (without angering the teachers like theyd id w/ algebra in ’08 by making the cut-off a 30).

      This test was out of 88, so feel free to speculate and analyze; but patience is a great virtue.

      We took the test, but the real test — it seems — is that of our patience.

      Best of luck to all.

      June 17, 2010 pm30 3:56 pm 3:56 pm

      The conversion chart is NOT based on any proportion.

      It’s not like 70 out of 88 is equal to x out of 100.

      Generally speaking, it’s possible for the Board of Regents to curve up or down (meaning that 1x could be a 98) or a 30 could be a 66.

      you are mistaken, Boris.

        Porgey, you are mistaken.

        the person is saying if her raw score is equal to 70…

        What do you think the phrase “raw score” means?

        It means out of 88 (which is the maximum # of pts that one could have earned on this particular Regents) An 88 is a 100, so the person is asking you to speculate what a 70 will be when it is converted when the Board of Regents finally releases the conversion chart.

        Juries have taken less time to convict people and send them to the electric chair than this Board of Regents i s taking to finally allay our fears and tell us whether we passed; I suppose it’s all for the best, though: they’re trying to decide just how low the cut-off should go.

      thats an 80 if you divide (70/88) i think that would be like an 83-85 converted and whatever this jd guy says is probably wrong he is giving such a vast range hes saying that anywhere from 70-78 raw points would be a 90. being that 70/88=80% i highly doubt u would get a 10 point increase with the curve since your at the point where the curve isnt so big anymore

    can someone explain number 24

    • Noel permalink
      June 17, 2010 pm30 2:17 pm 2:17 pm

      To answer your first question, 21) is (2) because r is defined such that |r| </ 1, where +/- 1 would symbolize strongest, but going higher than that doesn't make sense.

      24) Let theta = x
      cos^2x – cos 2x
      cos^2x – (2cos^2x – 1)
      cos^2x – 2cos^2x + 1
      -cos^2 x + 1

      From sin^2x + cos^2x = 1
      subtract cos^2x both sides

      sin^2x = -cos^2x + 1

      Thus answer is (1) sin^2 (theta)

    he didn’t say it would be 70-78 points- he said it could be anywhere in that range, as seen from past curves. so Jami could be right and so can you and maybe its somewhere in the middle of you both- I’d say it would be an 85.
    She said “What do you think a 70 in raw score would be worth” that sounds clear to me, Porgey. So why are you saying, “70 what?? jellybeans” if she said in the first question- raw score.
    Sigh. Now i see why they say book smart doesn’t mean street smart :) some people have no tact. Okay, so you didn’t understand her question- no one said you have to answer it, and don’t cover your mistake by saying she wasn’t clear.

    according to past math conversion charts:
    int. alg. jan 09- 77=90 and 68=85
    geometry june 09- a 77 raw= 90 and 71=85
    geometry aug 09- 76=90 and 68=85
    geometry jan 10- 77=90 and 70=85

    the first number is raw=real according to those conversion charts. These should give a good idea of what a 90 and 85 would be in raw score points. So, although your 70 would NOT be a 60, it would be most probably 87

    • Anon. permalink
      June 17, 2010 pm30 8:45 pm 8:45 pm

      That is correct. It’s the same answer I got. What could you have gotten? Noel’s work was correct, it’s squrt(-1 * 100 * 3) (-1 * 100 * 3 = -300), giving 10i squrt(3). Unless someone made a mistake on the answer key, in which case a lot of people are going to be very angry when they get their scores. (I might end up getting one wrong because of a scantron error, I’m not sure if people look over the MC after it’s graded by the scantron machine. But it wasn’t 6, it was 11, in which I missed the negative sign in the exponent the first time I did the problem.)

    • Noel permalink
      June 17, 2010 pm30 8:41 pm 8:41 pm

      It’s an arithmetic series.
      The first term is 1
      and it goes 1 + 3 + 5 + 7 + 9 + …. + 39

      The formula would be
      Tn = T1 + ( n – 1) d
      T n = (1) + (n-1)2
      Tn = 1 + 2n – 2
      Tn = 2n – 1
      or 2k – 1 as they said it, so that leaves us with choice 1 and 4
      Now it’s choice 1, because the top number represents how far it goes.

      To find where 39 is,

      39 = 1 + (n – 1) 2
      38 = 2n – 2
      40 = 2n
      n = 20

      Thus 39 is the 20th term

      So the answer is choice (1)

    • Noel permalink
      June 18, 2010 am30 12:38 am 12:38 am

      83

    • June 18, 2010 am30 12:49 am 12:49 am

      If passing is 49 and mastery is 73 (admittedly, those guesses are on the tough side), 66 would yield a 79.

      You can play this at home. Enter the following points in your calculator: (0,0), (pass,65), (mastery, 85), (88,100) and then perform a cubic regression. That’s how the state sets the scale.

      If passing is 47 and mastery is 70, 66 gives an 82.

      If passing is 44, but mastery is 74, (low pass, high mastery), 79.

      • Josh permalink
        June 19, 2010 pm30 12:53 pm 12:53 pm

        Where would you predict they set the mastery? I understand you can’t be really accurate, but that’s what’s going to destroy my score. Changing the passing doesn’t really help me at all, because my raw score is somewhere between 74 and 80 and I need at least a 90 or my parents will kill me…

      • Josh permalink
        June 19, 2010 pm30 1:28 pm 1:28 pm

        Do you think it would be feasible if they set them it as low as 64/65, considering that the mastery value for the June 2010 Math B’s (from looking at the conversion chart) seems to have been 70 and considering the fact that that exam has been administered for years now?

    Why is it a cubic regression?

    • June 18, 2010 pm30 3:01 pm 3:01 pm

      Because a cubic can be fit exactly to four points (ie, I can make it work without regression… but if you use the calculator, r = 1, a perfect fit)

      Is that a good reason? Absolutely not. They could use three line segments.

      In fact, if you look at the Geometry conversion chart, 71 is 85 and 86 is 100, but the scores do not go up one point at the time. Bizarrely stupid, don’t you think?

      I just don’t think Albany is good enough to make tests.

        “I just don’t think Albany is good enough to make tests.”
        I want to quote this somewhere. (outside this comment)

        I definitely agree. I had been worried about this test, but I seem to have done well on the M.C. The World History regents was a joke, and the chem regents ended up being harder than I expected. (From past tests. This year’s regents in chem had around 10 questions with traps that I saw) The A2/T fall sampler didn’t have that much correlation with that actual test, and although it wasn’t hard (for me), that was only because I was worried so much about it. (I even made a study sheet on the computer, which I almost never do. (a collection of useful facts that weren’t on the ref. sheet. (which I’d be glad to share if anyone wants it. It’s still on my computer.)))

          The sheet saved me a few points on the regents, and although I might have missed some things, and it is basically a compilation of random facts that I forgot or thought I would forget otherwise, but it helped remind me of things I did once then forgot. (such as completing the square)

      yes you have a shot for 2 reasons…first that may very well be the cut off for passing, you can never really tell what the state is going to do. second, lets say the cut is 40, your teachers have to regrade any exam that is above 60% scaled to see if they can find it points to get to a 65. if they graded a couple of your problems tougher, they may be able to squeak a few more points out of the test.

        the correct choice is 1. you cannot solve the problem that way. check it by graphing both equations into your calculator.

    • June 20, 2010 pm30 4:13 pm 4:13 pm

      Rule of thumb: When the radical is printed on the page in front of you, it means the principal square root (positive value) only. When you are doing work, and add your own radical symbol, then you need to consider both values (you are really asking the question, when I square what number will I get the thing in front of me).

      So solve for x: x^2 = 100, x could be 10 or -10, but
      Find the value of \sqrt{100}, that’s just 10.

      the curve doesn’t help the higher scores very much, they have to develope the curve for both passing and mastery. if your in the high 60’s great job, but until the 24th when the conversion chart is released anything anyone tells you is a guess.

      Also, please note that this is NOT the real conversion chart. This was just for fun.

    For the asymptote question…what did it mean by write the equation?

    • Mike permalink

      y = 0.

      The equation of the asymptote, the line that gets closer and closer to the x-axis but never touches it.

      Ever hesr of, “write the equation of this line given its slope and y-intercept”?

      y = mx+b

      Well, that’s an equation.

      In this case, they asked for the equation of the asymptote. I think that what threw off you (and most students) is not knowing the meaning of “asymptote”; if you knew what it was, you would probably have no problem writing the equation.

      Best of luck on the conversion chart,
      Mike

    for #37, how are we supposed to find the four solutions?

    sinx=sin2x

    i only got two, 60 and 360. i can see how 0 and 180 make sense, but how can you show that algebraically? and how many points out of 4 do you think i’ll get???

    • Anon. permalink

      First, 360 doesn’t work, since it was in the interval of greater than or equal to 0, but only less than (and not equal to) 360.

      Second, when you have Sin X = 0 and CosX=1/2, you don’t need to show anything else. It’s assumed that you know that when SinX = 0, X =0 and 180, and when CosX = 1/2 X = 60 AND 300.
      If you’re wondering why X=300, it’s because 60 is just the reference angle. Cosine is positive in the first and fourth quadrants, and 300 is in the fourth quadrant. (360-60 (ref angle) = 300)
      If two angles have the same reference angle, then the absolute value of Cos, Sin, and Tan are equal.
      In comparison, in the second quadrant, Cosine is negative, so where the reference angle is 60 (120), cosine equals -1/2. (note the negative sign.)

    I aced the Alg2/Trig regents because my teacher told the class to have their parents buy and use the Westsea Publishing NYS regents review workbook for Al2-Trig for homework every day.

    check it out. Uae it for summer school.

    i got a 72 out of 88.( which is an 81.8 so 82) what do you guys think are the chances of that being curved to an 85 ?

  55. Ryan permalink
    June 23, 2010 pm30 3:13 pm 3:13 pm

    Nicci—You’ll probably score between an 85 and an 88 depending on the curve. It comes out tomorrow; you can check online!

    Good luck!

    you may end up from anywhere from 80-90 if it’s a really good curve (hoping…)

    i was so thankful that the test was actually not as hard as i expected. supposedly a lot of people failed but imagine it was actually way more difficult. oh godd!

    yea this is like the first time that NYS has actually helped the kids who have gotten higher grades

    but i’m sure there are a lot of people who were hoping for passing to be at a much more accessible raw score than 46

    i mean for this year’s integrated algebra the passing raw score was 30 out of 87 so people who scored lower on this test are probably not very happy

    but i’m fine with it cause i got a 97% with an 81 raw score

    Hey guys, i failed my trig regent, and I’m retaking it tomorrow. Do they make a totally different test or do they use a new one (I’m studying using the june one and would hope that the questions are the same)

      It is a completely different exam. Good luck! =)
