Error: 
error: 'taylor' undefined near line 1 column 5

What does this error mean please?

I am using http://octave-online.net/.

See post at http://math.stackexchange.com/questions/209320/where-do-the-factorials-come-from-in-the-taylor-series.

See https://en.wikipedia.org/wiki/Taylor_series.

Documentation at http://octave.sourceforge.net/symbolic/function/@sym/taylor.html would be helpful if it included more clear examples, preferably ones which are complete.

You may use data sets to include tutorials if you wish, as I fail to see a complete implementation in place.

"'taylor' undefined" means it can't find the function, taylor. Do you have the symbolic package installed and loaded?

If you do 

pkg list

do you see a star next to symbolic?
