integral of 5+tan^2(x)

\int 5 + tan^{2} (x) d x

4 x + tan (x) + C

Solution steps

\int 5 + tan^{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 5 d x + \int tan^{2} (x) d x

\int 5 d x = 5 x

\int tan^{2} (x) d x = - x + tan (x)

= 5 x - x + tan (x)

Simplify

= 4 x + tan (x)

Add a constant to the solution

= 4 x + tan (x) + C

\int (cos (x) + 1) d x

\int - \frac{3}{2} x + 3 d x

\int \frac{1}{12 x ^{4}} d x

\int sin (x^{3}) 3 x^{2} d x

\int \frac{e ^{x} - 5}{x} d x
