Re: rk4
Hi;
The exact solution is
When I use RK4 with a step size of .2
The error is quite small. Can you figure the percentage error for yourself?
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: rk4
I have used Matlab but did not like it. I code in Mathematica.
