The Newell-Whitehead-Segel equation is an important model arising in biology, ﬁnance, ﬂuid mechanics and some more processes. Various researchers worked on approximate solution of this model by using diﬀerent methods. In this paper, the Newell-Whitehead-Segel equation of fractional order is solved by using a generalized Taylor series formula together with residual error function, which is named the residual power series method (RPSM). The illustrative examples are presented to demonstrate the accuracy and eﬀectiveness of the proposed method.
