Gersch Posted June 18, 2013 Report Share Posted June 18, 2013 Hey,So, I am doing the second SL folio, and for this I have some data. I have to investigate different functions which model the data. I have done about 16 pages and it is all going great, however we were hinted that putting an arctan function could help boost our grade. I would love to do this. But i dont know how to make this graph, as i have done all of my investigation using excel so far, and cannot find how to map one.Is anyone aware of a program (desmos, geogabra) and how to use it so that i may enter my data and it will generate an arctan function to map my data?

The Saint... Posted June 24, 2013 Report Share Posted June 24, 2013 You want to model an arctan function? Reply Link to post Share on other sites More sharing options...
Fermat Posted June 24, 2013 Report Share Posted June 24, 2013 Unfortunately, Geogebra does not have an arctan function (as far as I know). It has a bunch of other one's you might want to try. So if you need any help with Geogebra feel free to PM me. Reply Link to post Share on other sites More sharing options...
Gersch Posted June 25, 2013 Author Report Share Posted June 25, 2013 Its ok, thanks a bunch but I managed to map it using Desmos.comyou can create the function and use sliders to get a resonably accurate formula. Reply Link to post Share on other sites More sharing options...
