$$\int\limits_{0}^{1} \left(- 2 \cos{\left(x \right)}\right)\, dx$$

Integral(-2*cos(x), (x, 0, 1))

Detail solution

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

$\int \left(- 2 \cos{\left(x \right)}\right)\, dx = - 2 \int \cos{\left(x \right)}\, dx$
1. The integral of cosine is sine:
  
  $\int \cos{\left(x \right)}\, dx = \sin{\left(x \right)}$
So, the result is: $- 2 \sin{\left(x \right)}$
Add the constant of integration:

$- 2 \sin{\left(x \right)}+ \mathrm{constant}$

The answer is:

$- 2 \sin{\left(x \right)}+ \mathrm{constant}$
