Changing the range from "0" to "1" to "0.1" to "1" seems to fix the problem.

I hope this helps.

I'm not sure I would label it as a "trick". I can't read your worksheet, but I suspect it's more of a valuable lesson in numerical computing. I don't know what the function u(t) is, but I suspect that if you try to evaluate du(0) you will get a divide by zero error.
