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

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