Question

Evaluate integral tanx.dx..plss

Answer 1

Step-by-step explanation:

dx

set

u = COs x.

then we find

du = - sin x dx

substitute du=-sin x, u=COs x

(integral) sin x

COs x dx = - (integral)

(-1) sin x dx

COs x

= - (integral) du

u

Solve the integral

= - ln |u| + C

substitute back u=COs x

= - ln |COs x| + C
