I have an expression for infinitesimal length: [itex] F= g_{ij} \frac{dx^i dx^j}{du^2} [/itex] and by using Euler-Lagrange equation (basically finding the shortest distance between two points) want to find the equation for geodesics with affine parameter. But getting bogged in the indices and unable to extricate them so as to introduce the Christoffel symbols. Any help or suggestion on how to improve skills with this type of calculations is highly appreciated.
