I am trying to get the graphing function of the TI-89 Titanium working, but am having trouble.
I have the following settings just to try and get the graphing function to work.
Xscl = 1
Ymin = -10
Ymax = 10
Yscl = 1
When I go to graph, I get an ERROR: Dimension message and the only option is ESC-Cancel.
Can anybody please help me?
