Suppose that you are in a spatially flat universe containing a single component with a unique equation-of-state parameter w. What are the current proper distance dp(to), the luminosity distance dl, and the angular-diameter distance da as a function of z and w? At what redshift will da have a maximum value? What will this maximum value be, in units of the Hubble distance?
