$$\int\limits_{0}^{1} 3 \cos{\left(x \right)}\, dx$$ 
Integral(3*cos(x), (x, 0, 1))
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:
