Description
For inflationary models with nonminimally coupled scalar fields, we find more accurate expressions of the standard slow-roll parameters as functions of the scalar field. We propose new slow-roll equations. We check the accuracy of approximations considered, comparing them with numerical inflationary solutions founded without any approximations. Note that new slow-roll approximations have been constructed without the conformal transformation of the metric.
