Richardson-Tyrer method of solving differential equations

[James Richard Tyrer]

The previous posting for KMath reminds me that I was supposed to explain to 
someone my method (based on Richardson) of solving differential equations.

Is there a KDE application that solves differential equations (like Mathematica)?

Any way, if someone is working on this, please contact me and I will try to 
explain it.  Or, I will post it here if anyone asks.

It does work well -- it will solve an equation whose solution is:

	EXP(-K*T)*SIN(W*T)

Which is not easy to do by numerical methods.  Some methods tend to "blow up" as 
EXP(-K*T) should approach 0 (at T becomes large).

And it provides an error estimate.
