Topeco kalsonger ullared sin 2 (x)/cos 2 (x) + cos 2 (x)/cos 2 (x) = 1/cos 2 (x) We know that. sin 2 (x)/cos 2 (x)= tan 2 (x), and. cos 2 (x)/cos 2 (x) = 1. So the equation (i) after substituting becomes.

If f(2tanx/(1 + tan2x)) = 1/2(1 + cos2x)(sec2x + 2tanx) then find f(x).

What i needed help in proving was the form, $$\frac{2\cos x}{(1 - \sin x)^2},$$ which, according to @Atticus too, appears to be completely false. $\endgroup$ – … Question: Tan2 X / 1 + Tan2 X Dx.
