Thank you robphy. I can't say I understood much of the first article, but the second was right on the button. (Though I guess he must have left out a bracket in the equation starting L=, which had me going for a while). What I needed was a nice simple example like that. Now I will go...

I believe there is a way of calculating Christoffel symbols which is easier and less time-consuming than using the metric formula directly. This involves writing down the Lagrangian in a form that just includes the kinetic energy assuming zero potential energy and then equating the coefficient...

Thanks robphy. I'll have a look at those.

Hi, I am a new GR student and struggling a bit, to be honest. Usually in this situation I saturate myself with working through examples and eventually the penny drops, but I have not been able to find a text or any lecture notes etc. that provides examples of things like solving geodesic...
