But if Pallab's answer is correct, then it can be, right, at least for
this specific one?

The problem I see is *how* to add these to the integration routines.
There is no nice Meijer-G representation. And I suppose that Risch
can not handle these. At least not w/o major extensions.

WolframAlpha gives an answer in terms of an elliptic integral:
http://www.wolframalpha.com/input/?i=integrate(sqrt(sin(x)),%20x)
So I imagine that if we added those that we would be able to compute this.

It seems sympy can not integrate sqrt(sin(x)).
I did the following:
import sympy as sm
from sympy.abc import x,y,z
tointegrate=sm.sqrt(sm.sin(y))
sm.integrate(tointegrate)
output is : Integral(sqrt(sin(y)), y)
After a simple change of variable the integral is doable:
def ytoz(z):
return
