<p>Talking about the composite !</p>
<p>@massajim Yes, t=5 did affect the problem. But 5 seconds had passed, one of the dimensions had changed by 10 and the other had changed by 5. Then you had to differentiate and use related rates.</p>
<p>AB volume frq with calculator. what was the answer for the cross section isosceles one?</p>
<p>Do you think the curve may go below 68?</p>
<p>@sparkl3 the AP Calculus cut score had been very stable for many years. It is still going to be around 67-70 for a 5 despite how you guys think.</p>
<p>dang… i screwed up a few multiple choice but i think i still got a solid 5</p>
<p>@sparkl3 I put 400 something, I think it was around 448. I can’t remember, sorry. I talked to my friend afterward and she said she put 300 something but wasn’t sure if her integrand expression was written correctly. Do you remember what you had? Please say you had something between 400 and 500… please…</p>
<p>Number 28 on noncalculator MC on AB has been bothering me all day… Anything enlightenment me on what the hell it was asking? (The series looking one) Was thinking it was some trick question so was gonna guest either zero or infinite but I don’t really care so I just picked one of the integrals.</p>
<p>I’m expecting a solid 3 on the AB test. I thought the multiple choice was fairly straightforward, but the free response questions were killer. It was ugly.</p>
<p>@pretzel729 i think i put b (or maybe d) it had to do with reimann sum </p>
<p>Was the answer to the an and bn question bn converge so an converge?</p>
<p>I had 15 minutes left on the non calculator and 20 minutes left on the calculator part. And I felt like I did extremely well on all of it. Is that really abnormal? I did have to use all my time on the frqs because I didn’t know how to find the k value to separate the area into two equal parts, the related rates with the train, or any of the slope field question besides the actual slope field. </p>
<p>How much partial credit do they give on the frq? I think I messed up on 2 frqs D:</p>
<p>I’m going to be taking the AP BC exam in 2 weeks. Will it be the same test that you guys took? Someone reply please! :-* </p>
<p>Can anybody tell me an answer for this one? It was a MC question with a graph. I believe it was on the non-calculator part. It was the limit as X approaches 3 from the positive side of f(x)/x-3. The point given to us on the graph was (3,4) and it had zero slope. Thanks!</p>
<p>@Tragedies The test will be different.</p>
<p>@gsquared22 I think for that question I used l’hopital’s rule. But if you plugged in 4/(3-3) it was 4/0 and therefore undefined. SO you could use l’hopital’s rule. So you take the derivative of both the top and the bottom, so it became f’(x)/1. Since at the point (3,4), there was a maximum, there was also a horizontal tangent, thereby making f’(x) equal to zero. So 0/1=0. And Im pretty sure that was the answer. If you don’t know what l’hopital’s rule is, look it up. But im not sure if l’hopital’s rule was applicable here because it was not 0/0, or infinity/infinity, but I had no clue how to do it so I just used it anyways</p>
<p>I believe someone said the FRQs come out today?</p>
<p>Yup…they’re on the college board website: <a href=“AP Calculus AB Exam – AP Students | College Board”>Get the Most Out of AP – AP Students | College Board;
<p>Yeah, they are posted… But the answers and point values are not. Will college board post those today too? Or will they wait until after scores are released?</p>
