Homework Statement
∫tan^2(2x)/sec2x dx; u=sec2x; du=1/2tan^2(2x)dx.
Homework Equations
∫1/x(dx)-ln|x|+C.
∫1/u(du)=ln|u|+C
The Attempt at a Solution
This is me trying to rewrite the equation. (sin^2(2x)/cos^2(2x))/(1/cos2x), (sin^2(2x))/(cos(2x)).
Honestly, I feel lost trying to find a differential on the denominator, to change into the numerator.
