WebApr 20, 2024 · You can either use the expression for the Christoffel symbols in terms of the metric (remember that repeated indices imply a sum) or use the approach I suggested in #2. The second option is far easier from a bookkeeping standpoint so I suggest you try that. BBcode Guide Post reply WebOct 26, 2016 · The Christoffel symbols you dervied are indeed the correct ones for a spherical coordinate system $(r, \theta, \varphi)$. If you do the same procedure for a system $(r, \varphi, \theta)$ (in the metric tensor, the entries $(22)$ and $(33)$ are now swapped) you will get the Christoffel symbols as stated on Wolfram Mathworld.
