Can someone help me with R code to perform approximations to second order differential equations and systems of first order differential equations using Euler's method and Runge-Kutta? I am not a student and this is not for a test or graded assignment.
Examples (unrelated to each other): h = 0.1 1. 3(t^2)y'' - 5ty' + 5y = 0 y(1) = 0, y'(1) = 2/3 2. Lotka-Volterra x' = x(3-y) y' = y(x-3) [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
