integral of sin(x)+sin(x)cos(x)

\int sin (x) + sin (x) cos (x) d x

- cos (x) + \frac{sin ^{2} ( x )}{2} + C

Solution steps

\int sin (x) + sin (x) cos (x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int sin (x) d x + \int sin (x) cos (x) d x

\int sin (x) d x = - cos (x)

\int sin (x) cos (x) d x = \frac{sin ^{2} ( x )}{2}

= - cos (x) + \frac{sin ^{2} ( x )}{2}

Add a constant to the solution

= - cos (x) + \frac{sin ^{2} ( x )}{2} + C
