integral of 2sin(x)-2cos(2x)

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

- 2 cos (x) - sin (2 x) + C

Solution steps

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

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

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

= - 2 cos (x) - sin (2 x)

Add a constant to the solution

= - 2 cos (x) - sin (2 x) + C

What is the integral of 2sin(x)-2cos(2x) ?
The integral of 2sin(x)-2cos(2x) is -2cos(x)-sin(2x)+C
