Question

The integral of 2x/sin^2(x^2) dx

Answer 1

Can you pick a u substitution that might make that a bit easier?

Answer 2

since the top part is the derivative of the "x" on the bottom, this should just be a log answer.

Du(ln(u)) = Du/(u)

[S] 2x/[sin(x^2)]^2 dx

u = sin(x^2) du = 2x cos(x^2) .... i see the delimma lol

Answer 3

convert sin^2 to its identity:

sin^2 = 1+cos(2x)/2 maybe

Answer 4

decompose the fraction?
