Is the integral of sin(x/2) = -cos(x/2)

$\displaystyle \displaystyle\int \sin\frac{x}{2}~dx = -2\cos\frac{x}{2}+C$ But why?
Haha I need it for another problem, But thank you very much.
That was not what pickslides meant. Do you understand why the integral is $\displaystyle -2 cos\frac{x}{2}+ C$ rather than $\displaystyle cos \frac{x}{2}$?
