Numeric Reference for Points in Algebra View...
Dear GeoGebra friends,
I am hoping to be able to reference points numerically, so that in the Algebra View I can refer to them with an index parameter.
I haven't made this work, but this is what I tried. I named the points: A_1, A_2, A_3, and so on to A_10. Then I tried to make a sequence with the parameter, k, and the point A_k. It did not like that.
I then tried to name the points A1, A2, A3 and so on to A10. Then, I opened a Spreadsheet View hoping that I could see the points. (How do I do that?) Then, I hoped to return to the Algebra View and use the column number to somehow reference the points, like Ak, where k is a parameter. Again, it did not like this, interpreting the notation (rightly) as multiplication.
Basically, what I need is some sort of pointer, that can I can do arithmetic to and select points from. Any ideas would be most warmly received.
(If you are at all curious why I am interested in this: I play around with the mathematics of transport geography and I have been successful in illustrating some relationships between scheduling and connectivity [imagine changing bus lines with timed connections at every intersection!] with GeoGebra. This will model a full-in and full-out charter airline network and schedule.)
