Homework Statement
∫〖Sin^(2 ) x * cos2x dx〗
Homework Equations
The right answer should be: sin 2x / 4 - x/4 - sin4x / 16
The Attempt at a Solution
If i would set Sin^(2 ) x= (1-cos2x)/2 I can replace it in the integral
Then we get:
∫▒〖(1-cos2x)/2 cos2x dx〗
As far as I am concerned we cannot use the constant multiple rule because there is no constant to multiply
I don’t know how to go on from here to solve it
