$$\int\limits_{0}^{1} \tan^{2}{\left(4 x \right)}\, dx$$

Integral(tan(4*x)^2, (x, 0, 1))

Detail solution

Rewrite the integrand:

$\tan^{2}{\left(4 x \right)} = \sec^{2}{\left(4 x \right)} - 1$
Integrate term-by-term:
1. Don't know the steps in finding this integral.
  
  But the integral is
  
  $\frac{\sin{\left(4 x \right)}}{4 \cos{\left(4 x \right)}}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int \left(-1\right)\, dx = - x$
The result is: $- x + \frac{\sin{\left(4 x \right)}}{4 \cos{\left(4 x \right)}}$
Now simplify:

$- x + \frac{\tan{\left(4 x \right)}}{4}$
Add the constant of integration:

$- x + \frac{\tan{\left(4 x \right)}}{4}+ \mathrm{constant}$

The answer is:

$- x + \frac{\tan{\left(4 x \right)}}{4}+ \mathrm{constant}$
