integral of 2cos(x)-1

Solution

\int 2 cos (x) - 1 d x

Solution

2 sin (x) - x + C

Solution steps

\int 2 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 2 cos (x) d x - \int 1 d x

\int 2 cos (x) d x = 2 sin (x)

\int 1 d x = x

= 2 sin (x) - x

Add a constant to the solution

= 2 sin (x) - x + C
