integral of 3cos(x)+2/(sqrt(x))

\int 3 cos (x) + \frac{2}{x} d x

3 sin (x) + 4 x + C

Solution steps

\int 3 cos (x) + \frac{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 3 cos (x) d x + \int \frac{2}{x} d x

\int 3 cos (x) d x = 3 sin (x)

\int \frac{2}{x} d x = 4 x

= 3 sin (x) + 4 x

Add a constant to the solution

= 3 sin (x) + 4 x + C
