$$\int\limits_{- \frac{\pi}{3}}^{\frac{\pi}{3}} 4 \cos{\left(x \right)}\, dx$$
Integral(4*cos(x), (x, -pi/3, pi/3))
Detail solution
  1. The integral of a constant times a function is the constant times the integral of the function:

    1. The integral of cosine is sine:

    So, the result is:

  2. Add the constant of integration:


The answer is:
