Re: TI-85 graphing
On the TI-85 and 86, the ordered pair (1,2) represents the complex number 1+2i.
If you want to plot points, see page 4-39 of the TI-85 manual.
The command PtOn(1,2) will draw a point (turn on the nearest pixel) at x=1,
y=2.
The command Line(1,2,3,4) will draw a straight line from the Cartesian point
(1,2) to the Cartesian point (3,4)
