Abstract: The field equations of Kaluza-Klein (KK) theory have been applied in the domain of cosmology. These equations are solved for a flat universe by taking the gravitational and the cosmological constants as a function of time t. We use Taylor's expansion of cosmological function, $\varLambda$(t), up to the first order of the time t. The cosmological parameters are calculated and some cosmological problems are discussed.

Key words: Kaluza-Klein theory, cosmology, Taylor's expansion of cosmological function
