integral of e^x-4cos(x)

\int e^{x} - 4 cos (x) d x

e^{x} - 4 sin (x) + C

Solution steps

\int e^{x} - 4 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 e^{x} d x - \int 4 cos (x) d x

\int e^{x} d x = e^{x}

\int 4 cos (x) d x = 4 sin (x)

= e^{x} - 4 sin (x)

Add a constant to the solution

= e^{x} - 4 sin (x) + C
