1 / | | 1 | 1*--------- dx | 2 | cos (3*x) | / 0
$$\int\limits_{0}^{1} 1 \cdot \frac{1}{\cos^{2}{\left(3 x \right)}}\, dx$$
Integral(1/cos(3*x)^2, (x, 0, 1))
The answer (Indefinite)

/ | | 1 sin(3*x) | 1*--------- dx = C + ---------- | 2 3*cos(3*x) | cos (3*x) | /
$$\int 1 \cdot \frac{1}{\cos^{2}{\left(3 x \right)}}\, dx = C + \frac{\sin{\left(3 x \right)}}{3 \cos{\left(3 x \right)}}$$
