integral of cos(x)-3

Solution

\int cos (x) - 3 d x

Solution

sin (x) - 3 x + C

Solution steps

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

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

\int 3 d x = 3 x

= sin (x) - 3 x

Add a constant to the solution

= sin (x) - 3 x + C
