integral of 3+cos(x)

Solution

\int 3 + cos (x) d x

Solution

3 x + sin (x) + C

Solution steps

\int 3 + 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 3 d x + \int cos (x) d x

\int 3 d x = 3 x

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

= 3 x + sin (x)

Add a constant to the solution

= 3 x + sin (x) + C
