pi -- 3 / | | 2*sin(x)*x dx | / 0
$$\int\limits_{0}^{\frac{\pi}{3}} x 2 \sin{\left(x \right)}\, dx$$
Integral((2*sin(x))*x, (x, 0, pi/3))
The answer (Indefinite)
[src]
/ | | 2*sin(x)*x dx = C + 2*sin(x) - 2*x*cos(x) | /
$$\int x 2 \sin{\left(x \right)}\, dx = C - 2 x \cos{\left(x \right)} + 2 \sin{\left(x \right)}$$
