Approximate solution of generalized pantograph equations with variable coefficients by operational method
In this paper, we present an efficient direct solver for solving the generalized pantograph equations with variable coefficients. An approach is based on the second kind Chebyshev polynomials together with operational method. The main characteristic behind this approach is that it reduces such problem to ones of solving systems of algebraic equations. Only a small number of Chebyshev polynomials are needed to obtain a satisfactory result. Numerical results with comparisons are given to confirm the reliability of the proposed method for solving generalized pantograph equations with variable coefficients.
