(adsbygoogle = window.adsbygoogle || []).push({}); 1.a) Concider the 2-space consisting of a spherical shell at constan radius, r. In polar coordinates the line element on the surface can be written (a, b,∈ 1,2)

2. Relevant equations

ds^{2}=g_{ab}dx^{a}dx^{b}=r^{2}dθ^{2}+sin^{2}θdφ^{2}

calculate g^{ab}, Γ_{ab}^{c}, R^{1}_{212}, R^{2}_{121}, R_{11}, R_{22}, R

3. The attempt at a solution

I don't have an attempt on a solution cause I honestly have no idea how. Our teacher has said that it's possible to calculate the Christoffel sybols and the metric but he never showd how =/

really apprisiate any help

thanks a lot
