$\int_{0}^{\frac{π}{4}} \frac{\sin (2 x)}{1 + \cos^{2} (2 x)} d x$

Step 1

Once $\int_{0}^{\frac{π}{4}} \frac{\sin (2 x)}{1 + \cos^{2} (2 x)} d x$ has been evaluated, it will be constant with respect to $x$ , so the derivative of $\int_{0}^{\frac{π}{4}} \frac{\sin (2 x)}{1 + \cos^{2} (2 x)} d x$ with respect to $x$ is $0$ .

$0$
