How well do I need to know the trig-related functions/integrals for AB calculus.

<p>HI,</p>

<p>I know the test is over for most of U, but since I am taking the late test next wed..And I am still now cramming ...since I basically learned very few things in class..(not really my fault)....I feel so unprepared for the test..............and i got so confused by trig functions,,,I am just wondering if i Need to memorize all the sin, cos...and integral things............</p>

<p>You better know the trig functions and how to integrate them. Trig substitutions and trigonomeric power integrals (i.e. the integral of product of (sin x)^3 and(cos x)^4), I don't believe so.</p>

3

<p>k......thank you. so i only need to know the easy trig functions and integrations..right..but not the really complicated ones?</p>

4

<p>Antiderivatives following directly from derivatives of basic functions.
Antiderivatives by substitution of variables (including change of limits for definite integrals).
This is what CB says, so yes, you are right, although there are only six trig functions, and their inverses.</p>

5

<p>thank you!i feel much better now..</p>

6

<p>Just make sure you know the unit circle. Me & my friend reviewed the old one's I made the morning of the test and were very happy we did because they expect you to know the cos (pi/4)</p>

7

<p>thanks..and do i need to be an expert in related rates questions?</p>

8

<p>Not an expert... but there could possibly be an FRQ on related rates, knowing that there was no related rates problems on the regular scheduled exam. Good luck. :)</p>

9

<p>thats a good news....ususally...if the regular and late scheduled exams are somehow pretty similar</p>

10

<p>There actually was a related rates problem in the free response I think question 5 had a component.</p>

11

<p>oh make sure you know that unit circle i cept forgeting it (it was needed for one of the FRee resopnse q's)</p>

12

<p>my teacher told us that usually the ap only tests two of the inverse trig functions: sin and tan...because the rest of them you can get from those two...so if you remember those you should be fine...</p>

13

<p>how are you guys forgetting the unit circle or even having to study that? It's so easy to recreate the unit circle if you ever need it by just drawing 45-45-90 triangles and 30-60-90 triangles...</p>

14

<p>Here are some common ones you should know
derivatives of sin to cot.
integrals from sin to cot.</p>

<p>derivatives of arc sin to arc cot.
integrals of arc sin to arc cot.</p>

<p>this is if you really are aiming for a high score.</p>

<p>Note you can apply the chain rule to many derivatives (i.e. sin(x)^2. This is 2sin(x) (cos(x)).</p>
