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)

[edit] Physics exemple

I think the current discussion of the physics exemples could give the misleading impression that the Laplace equation only is useful in two dimensions. It is of course the case that the Laplace equation can be used in three-dimensional electrostatics and fluid flow (though my impression is that the cases in fluid mechanics where the Laplace equation can be applied are quite few) in the same way as in two dimensions. It is the connection with complex analysis that is lost. —Preceding unsigned comment added by 90.229.231.115 (talk) 19:52, 26 October 2007 (UTC)
