Foil 9 Basic Discretization of Single First Order Equation

From CPS615-Discussion of Ordinary Differential Equations and Start of Parallel N-Body Algorithm Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 10 October 96. by Geoffrey C. Fox *
Secs 135.3
For simplicity, we assume just one first-order equation, where f is the function on right hand side which depends on X and t
We can always solve this by setting up a grid of equidistant points with grid size h=(B-A)/n where n is an integer.
Starting from the initial value, we calculate positions one step at a time
