0 / | | 1 | ------------- dx | 2 | cos (2*x + 1) | / 0
$$\int\limits_{0}^{0} \frac{1}{\cos^{2}{\left(2 x + 1 \right)}}\, dx$$
Integral(1/(cos(2*x + 1)^2), (x, 0, 0))
The answer (Indefinite)

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