simple(?) simplification problem
Posted:

So I am calculating the gaussian curvature of an ellipsoidal surface, parametrized r(u,v) = a cos(v)cos(u), b cos(u)sin(u), c sin(v)
finding the first fundamental form yields for E
Ru = a cos(v)sin(u, b cos(v)cos(u), 0 So in the next step: Ru^2 I get (a* sin(v))^2*cos^2( u) + (b* sin(v))^2*sin^2( u) + (c^2 * (sin(v)^2)) ( http://img179.imageshack.us/img179/3680/possibletv4.png )
just wonder any way to simplify this? not keen on doing anything further with that one ;D nb, i suck at this
