Texas Instruments TI-83

TI-83 Plus Function Graphing 124

When the instruction is executed, the TI-83 Plus stores the value to the

window variable and displays the value.

@X and @Y

The variables @X and @Y (items 8 and 9 on the VARS (1:Window) X/Y

secondary menu) define the distance from the center of one pixel to the

center of any adjacent pixel on a graph (graphing accuracy). @X and @Y

are calculated from Xmin, Xmax, Ymin, and Ymax when you display a

graph.

@X = (Xmax N Xmin)

94 @Y = (Ymax N Ymin)

You can store values to @X and @Y. If you do, Xmax and Ymax are

calculated from @X, Xmin, @Y, and Ymin.
