integral of 3cos(x)+1

Solution

\int 3 cos (x) + 1 d x

Solution

3 sin (x) + x + C

Solution steps

\int 3 cos (x) + 1 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 cos (x) d x + \int 1 d x

\int 3 cos (x) d x = 3 sin (x)

\int 1 d x = x

= 3 sin (x) + x

Add a constant to the solution

= 3 sin (x) + x + C
