This demonstration shows
at its simplest. It generates
an approximate solution to the initial value problem
using step size dt=0.1. To advance one step click the "next" button.
To start over at t=0 click the "restart" button. The demonstration
provides a running commentary, which at each step tells you what the
current values of t, y and y' are and shows you the formula used to
construct the next value of y.
