Indefinite integration

[johngalt47]

I am trying to figure out how to use the Prime calculator to perform indefinite integrals.

I successfully entered the integration menu and typed in the integral I wanted to solve. The display shows the integral sign followed by my equation. When I press ENTER nothing happens. Do I need to press a different button to get the calculator to perform the integration?

BTW, my function is square root of sin x dx.
