Foil 18 Approximate solutions of the ODE for et at t=1, using modified Euler's method with different values of h

From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- 1998 Enhancements. by Geoffrey C. Fox


Note global error is now O(h2) and we get an error of O(10-5) after 128 iterations which would take about 1000 more iterations for Euler's method to achieve
So Euler has roughly half the computational effort per iteration but requires the square of the number of iterations
