integral of (tan^2(sqrt(x)))/(sqrt(x))

\int \frac{tan ^{2} ( x )}{x} d x

- 2 x + 2 tan (x) + C

Solution steps

\int \frac{tan ^{2} ( x )}{x} d x

Rewrite using trig identities

= \int \frac{- 1 + sec ^{2} ( x )}{x} d x

Expand

\frac{- 1 + sec ^{2} ( x )}{x} : - \frac{1}{x} + \frac{sec ^{2} ( x )}{x}

= \int - \frac{1}{x} + \frac{sec ^{2} ( x )}{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 \frac{1}{x} d x + \int \frac{sec ^{2} ( x )}{x} d x

\int \frac{1}{x} d x = 2 x

\int \frac{sec ^{2} ( x )}{x} d x = 2 tan (x)

= - 2 x + 2 tan (x)

Add a constant to the solution

= - 2 x + 2 tan (x) + C
