Is trig substitution in the ap calculus bc exam?
No
@skieurope Are you sure? I’m pretty sure you have to know how to take the integral of complex trig. Or I may be interpreting “trig substitution” simply wrong… but I’m assuming he’s referring to u-sub – related stuff.
@sjwon3789 I think OP is referring to integrating functions such as 1/(4 + x^2) dx, which is (relatively) easily done by substituting x = 2 tan u.
In that case, I honestly don’t remember if any problems on the exam required trig substitutions. I know we covered them in my BC class though. Best to check the exam syllabus or a sample test. Or better yet, be able to evaluate these integrals with trig substitution.
Why the heck isn’t it in the curriculum? It’s in every university’s calc 2. Now I have to self study this crap. The BC-only material is too skimpy to represent Calc II, that’s why rarely anyone uses the credit.
