$$\int\limits_{0}^{1} \frac{1}{\sin{\left(x \right)} - \cos{\left(x \right)}}\, dx$$

Integral(1/(sin(x) - cos(x)), (x, 0, 1))

Detail solution

Rewrite the integrand:

$\frac{1}{\sin{\left(x \right)} - \cos{\left(x \right)}} = - \frac{1}{- \sin{\left(x \right)} + \cos{\left(x \right)}}$
The integral of a constant times a function is the constant times the integral of the function:

$\int \left(- \frac{1}{- \sin{\left(x \right)} + \cos{\left(x \right)}}\right)\, dx = - \int \frac{1}{- \sin{\left(x \right)} + \cos{\left(x \right)}}\, dx$
1. Don't know the steps in finding this integral.
  
  But the integral is
  
  $\frac{\sqrt{2} \log{\left(\tan{\left(\frac{x}{2} \right)} + 1 + \sqrt{2} \right)}}{2} - \frac{\sqrt{2} \log{\left(\tan{\left(\frac{x}{2} \right)} - \sqrt{2} + 1 \right)}}{2}$
So, the result is: $- \frac{\sqrt{2} \log{\left(\tan{\left(\frac{x}{2} \right)} + 1 + \sqrt{2} \right)}}{2} + \frac{\sqrt{2} \log{\left(\tan{\left(\frac{x}{2} \right)} - \sqrt{2} + 1 \right)}}{2}$
Now simplify:

$\frac{\sqrt{2} \left(- \log{\left(\tan{\left(\frac{x}{2} \right)} + 1 + \sqrt{2} \right)} + \log{\left(\tan{\left(\frac{x}{2} \right)} - \sqrt{2} + 1 \right)}\right)}{2}$
Add the constant of integration:

$\frac{\sqrt{2} \left(- \log{\left(\tan{\left(\frac{x}{2} \right)} + 1 + \sqrt{2} \right)} + \log{\left(\tan{\left(\frac{x}{2} \right)} - \sqrt{2} + 1 \right)}\right)}{2}+ \mathrm{constant}$

The answer is:

$\frac{\sqrt{2} \left(- \log{\left(\tan{\left(\frac{x}{2} \right)} + 1 + \sqrt{2} \right)} + \log{\left(\tan{\left(\frac{x}{2} \right)} - \sqrt{2} + 1 \right)}\right)}{2}+ \mathrm{constant}$
