Collocation Approximation Method For Special Linear IntegroDifferentialequations Using Chebyshev Basis Function

In this paper, we consider the solution of first and second order Linear integro-differential by the use of trial solution formulated as Chebyshev form of Fourier cosine series. The behaviour of solution for different degrees (N) of the trial solution is carefully studied and illustrative examples are included to demonstrate the validity and applicability of the techniques.
