Abstract
Starting from the representation of a function as a formal power series with Taylor coefficients , we establish a formal series for the implicit function such that and the coefficients of the series for depend exclusively on the . The solution to this problem provided here relies on using partial Bell polynomials and their orthogonal companions.
