Help: Euler Algorithm

The Euler algorithm for the differential equation Y' = f(X,Y) (where X is the independent variable) is

Y(X + h) = Y(X) + h f(X, Y(X))

The step size is

h = (XF - XI)/N

where XI is the initial value of X, XF the final value and N the number of steps, as set in the Main window.
