Sect. 1.4: Approximation of Solutions to IVPs using Euler's Method To apply Euler's Method using this applet, you need to enter the following:
1) f(x,y): From your differential equation y' = f(x,y) (See the notes on the site for help on entering f(x,y))
2) x0 and y0: Initial Conditions
3) b: The x-value you want to end with
4) n: The number of intervals/steps
You need to select "Enter" and then clicking on "Run" will advance the approximation by each step until you reach b.
Sect. 1.3/1.4: Direction Fields and Approximation of Solutions to IVPs using Euler's Method This applet allows you to type in a differential equation of the form y' = f(x,y). It will show the direction field for a particular window. You can change the point that is the initial condition for the IVP by typing in a new point or simply dragging the given point. The solutions are approximated by using Euler's method. If you would like to see a "smoother" and more accurate solution, enter a smaller value for the step size h.
