<p>Oh shoot. I never bothered to memorize them during precalc.</p>
<p>ehhhh the senioritis had settled in too deep for me to care. and there's so much in calculus that isn't about trig identities, you can study long and hard and only come across them a couple of times.</p>
<p>but they're always there. . . lurking.. . .</p>
<p>The trig identities help when you're trying to make differentiation and integration a bit easier (getting past the chain rule or using an established anti-differentiation formula). You'll see when you get there.</p>
<p>I don't understand why everyone stresses the trig part of calculus so heavily. In my class, I never had to personally use anything more complex than sin^2+cos^2=1. Occasionally my teacher would use the double and half angle identities for an elaborate derivative by limits, but anything of that complexity will never show up on the actual exam.
P.S. Deriving all the trig function derivatives by the limit definitions is extremely painful....</p>

<p>I had a pretty good AP calc teacher to begin with. She gave us practice tests every class for the last 3 weeks before the AP exam. Very helpful, since they were graded. The exam, itself, wasn't too challenging either. I skipped a few on the non-calculator section and got almost all the calculator section correct. I missed a few points on the free response though... Oh well! Still a 5.</p>

<p>Took it because I like calculus (it didn't help me - you get the same credit at my college for AB and BC) after taking AB. The material was so, so much easier than EPGY, but my class never covered slope fields so I didn't answer the last free response question at all.</p>
<p>If you truly understand the reasoning behind the trig identities in pre-cal, you won't have to worry about memorizing all of them. Rather, you will be able to derive them really quickly during a test...</p>

<p>Calculus is fun.</p>
<p>Not really. But it's interesting.</p>
<p>wow, only 5's lol. that cc for ya...</p>

<p>this is ridiculous...i know cc is good but...</p>
<p>no one with anything other than a 5 better post their score...</p>
<p>lol ya i def think people got less, but don't wanna say anything</p>

<p>wootttt</p>
<p>hahah this is crazy...i'm not so sure people got less</p>
<p>I'm sure people did, just check the other thread where everyone's posting all their AP scores.</p>
<p>if i wanted to call again to hear my AP scores using the same credit card would it charge me twice?</p>
<p>lol...when I get my scores in the mail, 5 or NO 5, I'M POSTING IT HERE....</p>
<p>I got a 5, and I was pretty happy about it til I saw everyone here got a five. Please guys dont feel stupid because you got a 4, post it too. I got a 4 in AB last year and I don't consider myself stupid. </p>
<p>THE TEACHER WAS. :)</p>
