-pi ---- 4 / | | 1 | ------- dx | 2 | cos (x) | / pi -- 4
$$\int\limits_{\frac{\pi}{4}}^{- \frac{\pi}{4}} \frac{1}{\cos^{2}{\left(x \right)}}\, dx$$
Integral(cos(x)^(-2), (x, pi/4, -pi/4))
The answer (Indefinite)

/ | | 1 sin(x) | ------- dx = C + ------ | 2 cos(x) | cos (x) | /
$$\int \frac{1}{\cos^{2}{\left(x \right)}}\, dx = C + \frac{\sin{\left(x \right)}}{\cos{\left(x \right)}}$$
