Numerical treatment of mixed volterra-fredholm integral equations using trigonometric functions and laguerre polynomials

الملخص EN

In this paper, numerical solution of linear mixed Volterra-Fredholm integral equations of the second kind by using trigonometric functions and Laguerre polynomials approximation accompanied with the least square technique is presented.

For the explanation of the idea and more illustration, an algorithm is introduced, and several examples are solved.

Also, comparison between the exact and the approximate solutions are given to show the efficiency of the methods and accuracy of the results
