Abstract :In this paper, both linear Volterra and Fredholm integro-differential equations are considered. We propose  and  implement Exponentially  Fitted Collocation  Approximate Technique  insert ignore into journalissuearticles values(EFCAT); to  solve these types of equations. The collocated perturbed Integro-differential equations were transformed in to square matrix form which eventually solved using MAPLE 18 software. In order to investigate the accuracy of the solution with a finite number of computation length insert ignore into journalissuearticles values(N=8 and N=10); four examples were considered. To show the efficiency of the present method, numerical experiments are performed on some applied problems which have been solved by some existing methods and the numerical solutions are  compared with available results in the literature  and that of analytical solution. The numerical results obtain show the simplicity and efficiency of the method.
Keywords : Volterra and Fredholm integro differential equations, exponentially fitted collocation approximate technique, analytical solution
