Are the same than in the smath file?Best regards.Alvaro.

Slightly changed, maybe less correct posed, but solved correctly To excuse myself and thank Alvaro and Jean once more. I unintentionally deleted some regions regarding initial conditions and introduced a confusion a bit, and figured out by rechecking the things.

The troubles that I find solving this is that can't use the normal call for functions, as it is showed at the end, where fails to call the same Newton-Raphson code, but with F(1) and C(1).This must to be some kind of bug calling functions when the definition of the functions it's complicate or implies the vectorization for the args.

It might suffer sameauto-consumption than FindRoot, i.e: it does not clear itself within a for loop.It must be called from an external forloop. Will post soon a semi-elegant wayof descending the FindRoot that needs several iterations as it is ± 3 decimalsfrom the Smath native module. I get 0.0000000000001 as final sanity solutions.Takes ~ 5 minutes of manual iterations ... Jean is happy !Cheers Alvaro.

Primer38-undoomed - redoomed.sm (76kb) downloaded 34 time(s).Best regards.Alvaro.Thank you Alvaro for this. This was a logical thing to do in order to improve your function. Moreover, the "spooky" thing "xx-not defined" appears here and there and I often do not have a clue why. It often appears when you want to use eval(). Someone might have an explanation for this effect you represented in this example, but it still makes me confused and it seems it will remain that way. I suppose you understand now why I called this one as "doomed".Regards,Radovan When Sisyphus climbed to the top of a hill, they said: "Wrong boulder!"

Do I have a wrong understanding?Thanks again.

Simply a Classroom quick plot demo.What it plots is not otherwise possible to evaluate.However, you can play/productive with the spooky Taylor.Cheers ... Jean ... hope it clarifies.
