the first friedmann equation is:
In the case of a closed Universe (k > 0) containing only non-relativistic matter and no cosmological constant, write the Friedmann equation in terms of, H(a), H0, a and Ω0 (where Ω0 is the current matter density parameter). Assume that the current scale factor, a0 = 1
The Attempt at a Solution
so far what I have is:
I've seen things like
but I have no explanation for this and so can't tell if it's right.
