Question

Integrate : ∫ (xcosx)/(xsinx + cosx)^2 dx

Answer 1

its (xsin(x)+cos(x))^2?

Answer 2

if its like that then try substitude u=xsin(x)+cos(x)

Answer 3

\[\int\limits \frac{xcosx}{(xsinx+cosx)^2} dx\]

I'm sorry .. That's the correct question.

Answer 4

ok then let u=xsin(x)+cos(x) and solve

Answer 5

Done. Then du = xcosx-sinx

Answer 6

um no u have some mistake there

Answer 7

Oh!

Answer 8
