Official AP Calculus AB 2011 Thread

<p>I think that overall the exam was not that difficult (knock on wood). If you studied, you should have known every question on it. I did every problem since 98 and experienced similar problems before. I know I screwed up 5 [plugged in time instead of the other variable], but I am hoping that part c pulls me through.</p>

<p>does 9pi/4 -6 sound familiar</p>

<p>does 609 point something sound familiar</p>

<p>Can I get a breakdown of what it takes to get a five? Not just the percentage right. I want to know about how many mc and frqs u need right.</p>

<p>Yayy 1411, what a great year! Also, you know those times when second derivatives are always positive so the first derivative is increasing and the initial tangent line in an underestimate? God, I love those moments.
It has been 48 hours, right?</p>

<p>@futuresuccess I’ve calculated it many times for what I’d need and I would say for a 5, you need to get maybe 31 on both MC and FR (without muptiplier).</p>

<p>Somebody post their answers</p>

<p>@futuresuccess but that is without curve, for a 5 you’d need 68…but I actually bet it could be lower, like 63-66 ?</p>

<p>*multiplier</p>

<p>that means you’d need at least ~6 points average on each FR
and only 6 to 7 incorrect allowed from each MC section</p>

<p>are we allowed to talk about the questions yet?</p>

<p>yes, now we are.</p>

<p>so what did you guys get for 5c and 3b?</p>

<p>idr those. Did anyone get an answer inolving the constant e for 6c?</p>

<p>what did u get for the question about g(x)=2x + int of f(x) from x to 0</p>

<p>can someone put the link to the test</p>

<p>the inflection point was at x=0,</p>

<p>the abs max was at either 1.5 or 2.5 i dont remember</p>

<p>@ kmigasde I think i got x=0 as the inflection point and i got 2.5 as the abs max</p>

<p>the biscusts were 8.something cooler than the tea</p>

<p>it was 43-34.xx</p>

<p>u sure?? I got 609 point something degrees celcius</p>

<p>im not sure but i think so…when will we be able to see the answer key on college board?</p>

<p>I have nooooooooooooo idea</p>

<p>I remember the biscuits were somewhere in the 30s.</p>

<p>Here goes 5:
A. 1411 tons
B. Underestimate</p>

<p>C. W’’ = 1/625 (W-300)</p>

<p>D W = 300 + 1100e^(-1/25 t)</p>

<p>Hope someone got similar answers.</p>
