$$\int\limits_{0}^{1} \tan^{2}{\left(x \right)}\, dx$$

Integral(tan(x)^2, (x, 0, 1))

Detail solution

Rewrite the integrand:

$\tan^{2}{\left(x \right)} = \sec^{2}{\left(x \right)} - 1$
Integrate term-by-term:
1. $\int \sec^{2}{\left(x \right)}\, dx = \tan{\left(x \right)}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int \left(-1\right)\, dx = - x$
The result is: $- x + \tan{\left(x \right)}$
Add the constant of integration:

$- x + \tan{\left(x \right)}+ \mathrm{constant}$

The answer is:

$- x + \tan{\left(x \right)}+ \mathrm{constant}$
