In addition it becomes difficult to present the information appropriately, that is specifically important for the user. For some time, illustration, which is an application of non-photorealistic re...

the main purpose of this article is to present an approximate solution for the two-dimensional nonlinear volterra integral equations using legendre orthogonal polynomials. first, the two-dimensional shifted legendre orthogonal polynomials are defined and the properties of these polynomials are presented. the operational matrix of integration and the product operational matrix are introduced. th...
