Double Integration error with sin squared differential

Hi,

I am trying to solve the following double integral equation in Mathcad (Equation 17 extracted from tech paper). see bottom of attached Mathcad sheet.

I get an "a name is required here" error when using the d(sin(q)2) i.e "d sine squared" in the differential. Can I use this d(sin(q)2)? Is there a trick to getting the syntax correct? Many Thanks Ross

Hi,

Since the integration variables are theta and fi, the integration result is only a function of f. See next photo:
