Abstract

Based on Newton’s method, the authors developed Jarratt-type method. Also, the authors
theoretical convergence order by using Taylor series expansion. Further, the authors compared several
existing models with regard to the efficiency index of existing methods, whereas the efficiency index of
proposed method is 1.587 that are superior to Newton’s method.
