The System of nonlinear equation is then solved using iterative methods for obtaining the approximated solutions of nonlinear Volterra-Fredholm integro-di erential equations. Some numerical examples are given to compare their accuracy with the exact solutionenTriangular functionsnew representation of triangular functionsnonlinear integro-di erential equationsystem of nonlinear equationstudent Paper Post Degree
