# christoffel symbols of the second kind: how exactly to calculate?

Hello,
I have a function
f(u,v) = ( cos(v)*sin(u), sin(u)*sin(v), cos(u) )
which describes a sphere in R3.

How can I calculate the Christoffel symbols of the second kind? I didn't understand the examples I saw so far. I have no idea on how to proceed. Thank you for your efforts, Best wishes Hans
