### Re: Probably a No-Brainer

Wait a minute . . I think I got it: on mouseUp put 0 into m repeat 3 --(or any number) get fld "genFctn" put it&"+" after field "explFctn" replace n with m in fld "explFctn" add 1 to m end repeat

### Re: Probably a No-Brainer

You are so clever, Herman! Yes, the idea is to write it out into a field. This is great for the Taylor series, but how would one generalize this so that we could expand any fctn of x and n in the “genFctn” field into the “expandedFctn” field Sorry to take up so much of your time. Thanks,

### Re: Probably a No-Brainer

You don't want to compute it but want to write it out into a field? on mouseUp put taylorsum(4,"x") into fld "OUT" end mouseUp function taylorsum n,x -- n is the degree, x the function argument put "1" into s -- or: put x &"^0/0!" into s repeat with i=1 to n put " + " & x &"^"& i

### Re: Probably a No-Brainer

Thanks to Herman and Håkan but I haven’t got it yet. Consider the sum from n=0 to 2 of x^n/n!. What I want to do is expand this into the series x^0/0! + x^1/1! + x^2/2! etc. I can’t seem to wrap my head around this one!! Thanks very much, Roger > On Dec 27, 2018, at 8:25 AM,

### Re: Probably a No-Brainer

replace "x^n" with "x^" & n in field "formula" might do the trick… :-Håkan On 27 Dec 2018, 04:34 +0100, Roger Guay via use-livecode , wrote: > As an example, I want to replace the contents of a field that contains x^n > with x^1 or x^2 or x^3 as n= 1 or 2 or 3 etc. > But I can’t seem to find

### Probably a No-Brainer

As an example, I want to replace the contents of a field that contains x^n with x^1 or x^2 or x^3 as n= 1 or 2 or 3 etc. But I can’t seem to find find a script that works. Help please?? Roger ___ use-livecode mailing list use-livecode@lists.runrev.com
