∫ e x 2 + sin 2 x 1 + cos 2 x d x =
Options
- Ae x tan x + C
- Be x + tan x + C
- C2 e x tan x + C
- De x tan 2 x + C
Correct answer
A. e x tan x + C
Step-by-step solution
I = ∫ e x ( 2 + 2 sin x cos x 2 cos 2 x ) d x I = ∫ e x ( tan x + sec 2 x ) d x I = e x tan x + C ∵ ∫ e x f x + f ′ x dx = e x · f + C
