Numerical Methods for Solving Differential Equations

Euler's Method

Using the Method with Mathematica

(continued from last page...)

Back in the Introduction to this laboratory we went through a preliminary example "by hand". We commented that the work involved was tedious, and would be better suited to a computer.

We will now use our newly defined euler program to recalculate the numerical solution to the preliminary example. As a reminder, the problem was:

y′ = x + 2y

y(0) = 0

and we solved it by using 4 steps, up to an x-value of x = 1.

To make euler solve this problem, the appropriate command would be:

prelimsol1=euler[x+2y,{x,0,1},{y,0},4]

Go back to Mathematica and issue this command.

Let's go look at what you should have gotten...
