I have shown that for ##F(y,z)=0## it's Minkowski metric, but for ##F(y,z)\ne 0 ## I want to calculate Christoffel Symbols, Ricci tensor and scalar, the problem is that the metric ##g_{\mu\nu}## is not diagonal, and I need to find ##g^{\mu\nu}## in order to calculate christoffel and the rest, but how can I solve this without inverting the metric?

Thanks!
