Recursive functions and Advanced Graphing

[Sven44]

Thanks both for those answers.

I've switched to IFTE (wasn't familar with that), and that certainly seems to be an improvement in terms of just invoking the function from the home screen - as you say, handles larger numbers, and quite a bit faster in the simple graphing app too.

But still no luck in the advanced grapher. I think you're both right - it must be doing all kinds of clever optimisation, pre-compilation, interpolation or whatever else, and just can't handle recursive user-defined functions. (Even my factorial function, changed to using IFTE.) It does happily plot a simple user-defined function though, like Y=Squ(X), = X*X.

Oh well... it was probably asking a bit much!
