Problem with Simplify with Assumptions
Posted:

Hi,
I'm trying to simplify some expression with assumptions. When I input Simplify[x^2 + y^2 + z^2, p^2 == x^2 + y^2 + z^2] the output is x^2 + y^2 + z^2 (which fails to simplify).
But if I change the symbol names from x,y,z to a,b,c, i.e., Simplify[a^2 + b^2 + c^2, p^2 == a^2 + b^2 + c^2] the output is p^2 (it simplifies!).
How do I get Simplify to always implement this latter behavior irrespective of the symbol names?
Thanks in advance, Dave Snead
