You can them simplify, as follows, by putting it all over a common denominator: 2 / (1 + tan^2 x) - (1 + tan^2 x) / (1 + tan^2 x If we apply integration by parts to the rightmost expression again, we will get $∫\sin^2(x)dx = ∫\sin^2(x)dx$, which is not very useful. The trick is to rewrite the $\cos^2(x)$ in the second step as $1-\sin^2(x)$. Rewrite with only sin x and cos x.

In this section we look at how to integrate a variety of products of trigonometric functions. These integrals are called trigonometric integrals.They are an important part of the integration technique called trigonometric substitution, which is featured in Trigonometric Substitution.This technique allows us to convert algebraic expressions that we may not be able to integrate into expressions

We hope it will be very helpful for you and it will help you to understand the solving process. I tried: $(\sin^2(x))^2 = ((1-\cos2x)/2)^2$ but still getting $\cos x$ to the power of $2$. Wolframalpha only shows the answer which i have no idea how they got it. Could somebody help ? Using a Double-Angle Formula to Find the Exact Value Involving Tangent.
