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

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,

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

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

replace "x^n" with "x^" & n in field "formula"
might do the trick…

You could try to write in the file "x^[[n]] + x^[[n+1]]"
and then script
put 2 into n
put merge(fld 1) into fld 1
--> yields "x^2 + x^3"

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??
