We present an analytical solution for the luminosity distance in spatially flat cosmology with pressureless matter and the cosmological constant. The complex analytical solution is made of a real part and a negligible imaginary part. The real part of the luminosity distance allows finding the two parameters H₀ and Ω_M . A simple expression for the distance modulus for SNs of type Ia is reported in the framework of the mini-max approximation.
