Those above equations require the use of different equations for different times in the expansion of the universe. What I am looking for is one equation that can model the expansion for the entirety of the expansion.
Oh, well, the matter content of the universe changes with time, and the matter content determines how the expansion changes over time. So if you want to have one equation that models the whole expansion, it's going to have to take into account the matter content and how it's changed.
