Methods for obtaining exact solutions of the dynamical equations in Friedmann–Robertson–Walker spacetime for cosmological models with a scalar field and matter fields or nonzero curvature are considered on the basis of a representation of the main cosmological parameters as functions of the number of e-folds and direct substitution of the scale factor.
