I want to see if two expressions are equal. I have tried all of the methods outlined in this question but none seem to work.
I have two expressions,
\[CapitalSigma] = r^2 + a^2*Cos[theta]^2; \[CapitalDelta] = r^2 - 2*r + a^2; part1 = (-((3 a^2 r)/2) + r^3 -3/2 a^2 r Cos[2 theta])/((a^2 + (-2 + r) r) (r^2 +a^2 Cos[theta]^2)^2); part2 = (r*(r^2 - 3*a*Cos[theta]^2))/(\[CapitalSigma]^2*\[CapitalDelta]);
These two expressions are equal and so I expect
FullSimplify[part1 == part2] to return
True, but it does not.
