$$\int\limits_{- \frac{\pi}{2}}^{0} \sqrt{2 \sin{\left(x \right)} + 2}\, dx$$

Integral(sqrt(2 + 2*sin(x)), (x, -pi/2, 0))

Detail solution

Rewrite the integrand:

$\sqrt{2 \sin{\left(x \right)} + 2} = \sqrt{2} \sqrt{\sin{\left(x \right)} + 1}$
The integral of a constant times a function is the constant times the integral of the function:

$\int \sqrt{2} \sqrt{\sin{\left(x \right)} + 1}\, dx = \sqrt{2} \int \sqrt{\sin{\left(x \right)} + 1}\, dx$
1. Don't know the steps in finding this integral.
  
  But the integral is
  
  $\int \sqrt{\sin{\left(x \right)} + 1}\, dx$
So, the result is: $\sqrt{2} \int \sqrt{\sin{\left(x \right)} + 1}\, dx$
Add the constant of integration:

$\sqrt{2} \int \sqrt{\sin{\left(x \right)} + 1}\, dx+ \mathrm{constant}$

The answer is:

$\sqrt{2} \int \sqrt{\sin{\left(x \right)} + 1}\, dx+ \mathrm{constant}$
