Question from tariq, a teacher:

find integration

Sqrt(sinx) dx , from x=bi/4 to 3bi/4

Tariq,

This is not an elementary integral is is an elliptic integral of the second kind. I used Mathematica, in particular The Integrator web site to evaluate the integral. You can try this yourself. Go to The Integrator web site and put Sqrt[Sin[x]] into the integration form to see Mathematica's form of the indefinite integral.
