2012 AP Calculus AB Test Discussion

<p>I did get 4 for the first time then I got -4 but as I was drawing the graph, I think it was 3x^2+2x and 8x. They intersect at x=2. 8x is the top function so put that in calculator and see what you get.</p>

<p>okay…i think for that one i just integrated from 0 to 2 (3x^2 + 2x - 8x)…i didn’t have time to draw it out and see which one should have been subtracted from the other. but yeah that’s how i got -4. did you guys get 7pi/4 for one mc?</p>

<p>But it’s 4, right?</p>

<p>And i got 5pi/4</p>

<p>i think freddyo is right. i put it in the calculator and it’s 12, not 4 or -4 lol. and i was debating between 5pi/4 and 7pi/4 but i thought it would be seven because that’s where cos is positive and sin is negative but they have the same value so they=0? idk man that one confused me.</p>

<p>What did everyone get for which equation has a horizontal asymptote of -2 and 2</p>

<p>@tenisgirl do you remember the options? i kind of recall that question. i’m pretty sure i factored the top and the bottom, and then looked at the ratio of the degrees in the numerator and denominator.</p>

<p>@ flower and fred</p>

<p>I just put it in my calc and i got 4? :/</p>

<p>Mm well could you type on here what you entered? Let’s see what you do wrong there.</p>

<p>@mathisfun what did you put in? i might have done it wrong accidentally, but i put in integral from 0 to 2 8x-2x^2+3x (whatever the other function was haha).</p>

<p>by the way how did you get 5pi/4 :(</p>

<p>Yeah FR questions comes out tomorrow</p>

<p>I didn’t do great on the non MC & not perfect on all the frq . Had a bit of a crisis& left one calculator FRQ blank. I am doomed? I’d really appreciate if anyone has any idea!</p>

<p>honestly i think you can still score well (a 4) but probably not a 5. i’m kind of in the same position as you…screwed up a whole frq (probably a 1 or 2/9) and thought the last one was trickier than it should have been. i feel like everyone else thought the test was easy on here, but i’m still hoping for a good curve :D</p>

<p>Thanks flowerpower22!</p>

<p>Do you say this based on some sort of calculation?</p>

<p>appass.com :slight_smile: i would bump up the point distribution 2 or 3 because it seems like this was seen as an “easier” test but idk for sure obviously</p>

<p>@flowerpower
A and B i forgot
i know C and D both had square roots in them
E had (x+1)^2 in the numerator i think…</p>

<p>yah i don’t really remember. probably one with squared in the numerator though. did anyone get the 7pi/4 v. 5pi/4 question?</p>

<p>@flowerpower22</p>

<p>okay! I didn’t know how accurate appass is!</p>

<p>Hey guys, just wondering, if I forget a dt or dx or dy or put the wrong one after an integral, did I lose the complete point for the answer and something else?</p>

<p>PEOPLE! NEVER are you supposed to discuss specific multiple choice questions with ANYONE! Also, it has not been 48 hours since the test so you can’t discuss the free response right now either.</p>
