## Homework Statement

[/B]

I am trying to compute ##R## from the 3-d metric: ##ds^{2}=d\chi^{2}+f^{2}\chi(d\theta^{2}+sin^{2}\theta d\phi^{2})##

## Homework Equations

[/B]

The space also satisfies the below relationships:

##R=3k##

## R_{abcd}=\frac{1}{6}R(g_{ac}g_{db}-g_{ad}g_{bc})## [1]

## The Attempt at a Solution

[/B]

I think I need to compute the christoffel symbols, then the Riemann tensor, and contract etc.

I'm just wondering whether the task is meant to be simplified by eq [1]?( I can see the metric is diagonal and so this reduces the number of non-zero christoffel symobols...)

Thanks in advance.
