Here we present a new approach to deal with first order ordinary differential equations (1ODEs), presenting functions. This method is an alternative to the one we have presented in [1]. In [2], we have establish the theoretical background to deal, in the

Integration of a Class of Transcendental Liouvillian Functions with Error-Functions, Part II
The first part of the paper [J. Symb. Comp. 13, 525-543 (1992; Zbl 0759.12001)] described an algorithm which determines whether an element of a certain class of transcendental Liouvillian functions has an erf- elementary integral, i.e. an integral built up from elementary functions and error-functions, and which calculates it in case of existence. Here
