7 / | | /pi*x\ | |x|*cos|----| dx | \ 7 / | / 0
$$\int\limits_{0}^{7} \cos{\left(\frac{\pi x}{7} \right)} \left|{x}\right|\, dx$$
Integral(|x|*cos((pi*x)/7), (x, 0, 7))

/ / | | | /pi*x\ | /pi*x\ | |x|*cos|----| dx = C + | |x|*cos|----| dx | \ 7 / | \ 7 / | | / /
$$\int \cos{\left(\frac{\pi x}{7} \right)} \left|{x}\right|\, dx = C + \int \cos{\left(\frac{\pi x}{7} \right)} \left|{x}\right|\, dx$$
