In this paper, we consider an initial value problem y' = fi x, y), yi 0) = Y0, where f is a continuous function satisfying a Lipschitz condition. First, the function fix, y) is approximated by a Bernstein polynomial in two variables, Bnif; x,y), of an appropriate degree according to a prescribed acc

✦ Synopsis
In this paper, we present a method for approximating the solution of initial value ordinary differential equations with a priori error bounds. The method is based on a Chebyshev perturbation of the original differential equation together with the Frobenius method for solving the equation. Chebyshev polynomials in two variables are developed. Numerical results are presented.
