$$\int\limits_{0}^{1} \sin{\left(\frac{x}{4} \right)}\, dx$$ 
Integral(sin(x/4), (x, 0, 1))
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. Now simplify:

  3. Add the constant of integration:

The answer is:
