Question

intregation of e^x cos^2(e^x)dx​

Answer 1

in which class do you study the question is very different from ours

Answer 2

Step-by-step explanation:

Assume e^x = t

differentiating both sides

e^x dx = dt

above integrand will become :

t cos^2t dt

Then use Cos2x = 2cos^2x - 1

which gives Cos^2x = (1 - Cos2x)/2

Above integrand will become

t. (1 - cos2t) /2 dt

Then use u.v integration method.
