- Homework Statement:
- Find Ricci and Riemann tensors of FRW metric

- Relevant Equations:
- \begin{align*}g_{\mu\nu}=a(t)^2\begin{pmatrix} \frac{1}{1-kr^2} & 0 & 0 \\ 0 & r^2 & 0\\ 0 & 0 & r^2\sin^2{\theta} \end{pmatrix}\end{align*}

I just need to compare my results of the Ricci and Riemann Tensors of FRW metric, but only considering the spatial coordinates.
