Talk:Laplace's equation

From Wikipedia, the free encyclopedia

hi, one question! what is laplacian equation in toroidal coordinates(r,phi,theta)? tnx alot i waite for your answers bye


{1 \over r^2}{\partial \over \partial r}(r^2 {\partial f \over \partial r}) + {1 \over r^2\sin\theta}{\partial \over \partial \theta}(\sin\theta {\partial f \over \partial \theta}) + {1 \over r^2\sin^2\theta}{\partial^2 f \over \partial \phi^2} = 0


I just wanted to comment that this is an excellent article and, in particular, it's written very well!Andrei r 18:50, 21 February 2007 (UTC)
