<p>Is it just me or do the FRQs seem easier than multiple choice? FRQs seem to test just the basic knowledge of stuff…like you can get a 7/9 on almost every one without even attempting part D.</p>
<p>^We should combine our brains because I do well on MC, but I average 4.5 points per FRQ.</p>
<p>Also, for the official FRQ answers/scoring rubrics, is there any reason why, when the limit for an integrand is really long (ex: -1.63324), CB just says “Let a=-1.63324!” Is it because they are just too lazy to type the numbers or should I do that on the AP?</p>
<p>1 week left…</p>
<p>3 days left…</p>
<p>Everyone is busy cramming lol</p>

<p>A really good archive of student responses on the FRQ.</p>
<p>Multiple choice has always been my strength. However, the FRQs will be my downfall. Anybody understand optimization? I never really picked up the concept. Or does it play too minor of a role on the exam for it to be practiced?</p>
<p>futfsu1, for optimization, you just take the derivative and set it equal to 0</p>
<p>Hey, I don’t understand how to find limits with trig functions</p>
<p>Goya fairly solid 5 on a practice test yesterday, feeling pretty good</p>
<p>@kimmylouie can you give me an example problem and I’ll do my best to help. Limits are second nature to me by now.</p>
<p>is optimization on the test? if so, what types of problems?</p>
<p>This is going to be a piece of cake</p>
<p>@collegedream29
Of course it will be on the test. You need to now things like optimizing areas (given a certain amount of fencing, optimize area within).</p>
<p>When was the last time optimization was on there? I can’t recall it in a while. </p>
<p>It seems the newer released exams emphasize some the later Calc lessons, such as area/volume, inverse trigs, and differential equations.</p>
<p>@kimmylouie
Well for starts, (cosx-1)/x=0 if approaching 0 and (sinx)/x=1 if approaching 0 also</p>
<p>Guys, can you’ll outline some important topics to cover up now please?!
Any ideas on the FRQ’s and topics that have higher chances of turning up on the paper?</p>
<p>I think FRQs regarding FTC are so common. Look over those for sure.</p>
<p>Hi can someone help me with these problems?</p>
<p>f(x) = 3 + Integral (5x, -1) of t^3dt , find f ’ (x). </p>
<p>F(x) = integrand (x, 0 ) of sqrt(t^3 + 1) dt then F ’ (2) = </p>
<p>& this one</p>
<p>F(x) = Integrand (x , 0 ) of Sqrt(x^3+1) dt</p>
<p>Also there is another type of problem I need help with but its more of a concept thing
I am not really sure what it is called but its when they give you a point on the original function and you write the integral with a # + Integral (_<em>, _</em>) its like its similar to 2008 question #4. (a).</p>
<p>Guys, how do you tell if something is an overestimate or an underestimate?!</p>
