integral of-5sin(x)+9cos(x)

\int - 5 sin (x) + 9 cos (x) d x

5 cos (x) + 9 sin (x) + C

Solution steps

\int - 5 sin (x) + 9 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 5 sin (x) d x + \int 9 cos (x) d x

\int 5 sin (x) d x = - 5 cos (x)

\int 9 cos (x) d x = 9 sin (x)

= - (- 5 cos (x)) + 9 sin (x)

Simplify

= 5 cos (x) + 9 sin (x)

Add a constant to the solution

= 5 cos (x) + 9 sin (x) + C
