Summary
Many problems can be modeled by fractional Integrodifferential equations from various sciences and engineering applications. The authors in [1, 2] applied collocation method for solving the following: nonlinear fractional Langevin equation involving two fractional orders in different intervals and fractional Fredholm Integro-differential equations. Chebyshev polynomials method is introduced in [3,4,5] for solving multiterm fractional orders differential equations and nonlinear Volterra and Fredholm Integro-differential equations of fractional order. The authors in [6] applied variational iteration method for solving fractional Integro-differential equations with the nonlocal boundary conditions. In this paper least squares method with aid of shifted Chebyshev polynomial is applied to solving fractional Integro-differential equations. We are concerned with the numerical solution of the following linear fractional Integro-differential equation: Dαφ (x) = f (x) + ∫ K (x, t) φ (t) dt, 0 ≤ x, t ≤ 1, (1). Where Dαφ(x) indicates the αth Caputo fractional derivative of φ(x); f(x), K(x, t) are given functions, x and t are real variables varying in the interval [0, 1], and φ(x) is the unknown function to be determined
