New issue report by [EMAIL PROTECTED]:
Suggestion is to automate trigonometric simplification for following types
of expressions (should also work for hyperbolic expressions) which occur
in coo

Comment #1 by [EMAIL PROTECTED]:
The following code worked for the cases in comment 1. I don't know if it
would work
if there are more than two (theta and phi) trigonometric variables.

I am new to SymPy, so I may have missed a more straight forward method:
I have found the following quite useful in simplifying trigonometric

The OP expresions now give
eq3=r**2*cos(theta)**2*sin(phi)**2
eq1=cos(theta)**2 + cos(phi)**2*sin(theta)**2 +
sin(phi)**2

Currently you could use a poor man's trigsimp:
In [18]: e
Out[18]:
22 22 2 22 2
r ⋅cos (φ) + r ⋅sin (φ)⋅sin (θ) - r ⋅

Maybe we should add a flag to trigsimp (not sure what it should be called)
that just implements this simple simplification. This method can, I think,
be very inef
