Hey FilipVz.

This looks like a chain rule problem. Just to clarify, are these tensor indices? (Note that a non-zero Jacobian implies that a bi-jection exists between co-ordinate systems if I recall correctly). - Oct 11th 2013, 01:10 AMFilipVzRe: Partial derivation, Kronecker delta
Hi, chiro,

Yes those are tensor indicies. Do you have any idea how to solve the problem. Thanks in advance.:) - Oct 11th 2013, 03:34 AMchiroRe: Partial derivation, Kronecker delta
Its been a while since I actually did problems with tensors, but try finding the tensor expression for the chain rule in many variables (there has to be a compact form somewhere).
