<p>predictions for bc curve? and does anyone remember what they got for some of the multiple choice?</p>
<p>@Amad27 yes, I understand that if f(a)=f(b), then the MVT reduces to Rolle’s theorem. I just object to saying that Rolle is a corollary of MVT since, at least how I’ve done it, proving MVT theorem requires you to already have Rolle, so I’d say that MVT is a result following from Rolle, not the other way around. </p>
<p>The university I’m going to uses Apostol, so I’ll definitely take a look.</p>
<p>@Amad27 yay thanks! :D</p>
<p>How was the exam difficulty-wise? I’m writing the late exam next Thursday. </p>
<p>Any suggestions from those of you who already took the exam? I’ll be testing on Thursday during the late exam period.</p>
<p>I took the exam and it wasn’t that bad at all. Pretty sure I got 100 percent on the FRQs and either 100 percent on the calc MCs or I got 1 wrong, i narrowed it down to two choices and guessed. Hardest part of the test was the non-calc MCs and that wasn’t even bad. </p>
<p>My recommendations: Try doing 2013/2014 released FRQ, if you can do them relatively easily, I’d say you’re set.</p>
<p>For Calc MCs: Complete joke, just make sure you’re calculator is in radians and you’ll breeze through it even if you’re bad at Calculus</p>
<p>For Non-calc MCs: Know basic derivative/ integration formulas, know how to solve limit problems.
Know the Fundamental theorem of Calculus, ie; the derivative of integral f(x) = f(x), i remember a lot of problems that are very easy but FTC is essential to solve them.</p>
<p>If you actually learned the material during your class this year, I honestly wouldn’t worry about it. The AP exam was easier than the regular tests my teacher gave us throughout the year. Just make sure you show your work on the free response.</p>
<p>Oh and also, know the volumes of a solid of revolution stuff like the shell, disk, washer method. If it’s a washer method remember to multiply by pi, I did a MC twice and one of the options was what you get if you didn’t multiply by pi and the other was if you did so that could have tricked a few people</p>
<p>Talk about reassuring! Thanks a ton. </p>
<p>Are you guys ready for the exam tomorrow? :D</p>
<p>I sure am. Funnily enough, I found the 2014 FRQ questions to be more challenging than the ones in prior years. </p>
<p>for people who took calc ab today (may 22), what did you get for that question of the 28 question MC where they tell you to find f’(5)? and they give you something like g(f(x)) and f(x) g(x) and g’(x)</p>
<p>for the second part for FRQ’s, the question with the accumulation graph where g(x) = x + f(x), part d, what did you get for the absolute max? i for got the value but was it at g(7)?</p>
<p>What about the last MC of part a? The one about the sum as n approaches infinity of the summation of (3k/n)^2 * (3/n)? </p>
<p>@Seiyaryu I got 1/3 for 28. Just do the chain rule and plug in to get the answer.</p>
<p>Absolute max, take the derivative of g(x) to get 1 + f ’ (x). Then check your End Points and Critical points. I got g(5) to be the right answer. g(5) equaled 9/2 +2pi and g(7) equaled 7/2 + 2pi.</p>
<p>lol everybody was asking that, i guessed something with 9, either 9 or 19 w.e, for that f’(5) question i got 1/4
for the absolute max question, the derivative is 1+ f’(x), where did u get pi in your answer from because for f prime part u just basically look for the point of the graph, since f’(x) was given</p>
<p>I took the late exam today as well. What did everyone get for 6a and d? For 6a I got -1/50(250-H) which came out to -2. I have absolutely no clue what the limit was as h approached infinity. I believe h(t)=250-250e^-t/50 though. </p>
<p>h(t) is correct and limit came out to 250</p>
<p>for that 6a, its -100/2500</p>
<p>@Siyaryu: Seriously? I totallly missed 6b, but I guessed 250 on the last one with a bogus proof. :/</p>
<p>6a) dh/dt = 1/50(250-H) , asking for second derivative, so dh/dt 5 - (1/50)H simplified, second derivative:
(-1/50)H’ aka (-1/50)(1/50)(250-H)
h = 150, plug it in, its -100/2500</p>
<p>Yeah I bombed 6a and 6d then lol. Oh well. Let’s be real you can get exactly half of the multiple choice right and half of the open ended right and pull a 4. Anyone remember the function you had to write for total acres on the interval 24<x<33. It was like a weed killer kills the weeds at a rate of 15 acres per month or something. And then the absolute minimum? The function was f(t)= (10t/t+1)(1-sin(xpi/6)</p>
<p>Is the grading curve for the rewrite higher? I thought I had a solid understanding of all of the concepts, but my concentration level throughout the test was abysmal so I didn’t check any of my work. I’m almost definite that I scored a five, but what are the requirements for a four just in case?</p>
<p>hey guys, just wondering, for those who took the AP Calc BC exam, which prep book did you use and how relevant/useful would you say the information/practice tests were?</p>
