Integral(sqrt(1 - cos(x)/2), (x, 0, 2*POST_GRBEK_SMALL_pi))
Rewrite the integrand:
The integral of a constant times a function is the constant times the integral of the function:
Don't know the steps in finding this integral.
But the integral is
So, the result is:
Add the constant of integration:
The answer is:
