A method for the numerical integration of ordinary differential equations [PDF]

open access: yesMathematics of Computation, 1958
where y(x) denotes the solution of the differential equation. The idea is to use a quadrature formula to estimate the integral of (1). This requires knowledge of the integrand at specified arguments xi in (x0, xo + h)-hence we require the values of y(x) at these arguments.
