$$\int\limits_{0}^{\frac{\pi}{3}} \sin{\left(\frac{x}{2} \right)}\, dx$$
Detail solution
  1. Let .

    Then let and substitute :

    1. The integral of a constant times a function is the constant times the integral of the function:

      1. The integral of sine is negative cosine:

      So, the result is:

    Now substitute back in:

  2. Add the constant of integration:


The answer is:
