Friedman equations from flat FRW universe line element

[Seetesh]

I would like some help in calculating the basic Friedman equations starting from the flat FRW universe line element, Once I have calculated the Christoffel symbols for this metric how do i get to the Friedman equation, any link to a good book will be really helpful, thanks, seetesh.

Are you familiar with the Einstein Field Equations? The Friedmann equation comes from the 0-0 component.

Like Cristo said, it's the 00 component of Einstein equation so you will have to calculate

R_{00} - \frac{1}{2} g_{00} R

and set this equal to the zeroth component of the stress energy momentum tensor times 8 pi G
