1. The problem statement, all variables and given/known data Find all killing vectors of the 2-sphere. 2. Relevant equations [itex] ds^2=dθ^2+(sinθ)^2d\phi^2[/itex] 3. The attempt at a solution The goal of this problem is pretty self-explanatory; however, I didn't feel that the topic of killing vectors was covered very well in my course. I was just wondering if someone knew of a site which explained how to approach this sort of problem and the steps which need to be taken. Thanks in advance!
