We propose a general inverse formula for extracting inflationary parametersfrom the observed power spectrum of cosmological perturbations. Under thegeneral slow-roll scheme, which helps to probe the properties of inflation in amodel independent way, we invert the leading order, single field, powerspectrum formula. We also give some physically interesting examples todemonstrate its wide applicability and illuminate its properties.Comment: 8 pages, no figure ; References expande
