$$\int\limits_{\frac{\pi}{4}}^{\frac{\pi}{2}} \left(\cot^{2}{\left(x \right)} + 1\right)\, dx$$

Integral(1 + cot(x)^2, (x, pi/4, pi/2))

Detail solution

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

$- \frac{1}{\tan{\left(x \right)}}$
Add the constant of integration:

$- \frac{1}{\tan{\left(x \right)}}+ \mathrm{constant}$

The answer is:

$- \frac{1}{\tan{\left(x \right)}}+ \mathrm{constant}$
