Document Summary

Mat136h1 s - lecture 15 - calculus 1(b) Trig integration let u = sec x + tan x du = sec x tan x + sec2 x. I = for i= tan m x secn x dx. If m is even, and n is odd, change tan m x to tan2 x m. 2 = sec2 x 1 n 2 n 1 secn 2 x tan x + 2 and get secx power and use a. 2 ln sec x + tan x + c what if there are products of sin and cos? in the form of sinacosb. ) = sin a cos b cos a sin b. + sin a + b = sin a cos b + cos a sin b sin a b. 10/02/2017 find i= sin 3x cos x dx when a=3x,b=x. 4 cos 4 x] + c cos 2x 1.
