integral of (sin(x)+2)

\int (sin (x) + 2) d x

- cos (x) + 2 x + C

Solution steps

\int sin (x) + 2 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 2 d x

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

\int 2 d x = 2 x

= - cos (x) + 2 x

Add a constant to the solution

= - cos (x) + 2 x + C
