† GRAPH ZOOM menu
ZInt
Sets the window variable values so that each pixel is an
integer in all directions (
@ x = @ y = 1 ), sets xScl = yScl = 10 ,
and then updates the graph screen.
The current cursor location becomes the center of the
new graph.
One of the benefits of ZInt is that you can trace in whole
number increments.
In Func graphing mode:
y1=der1(x 2 N20,x) b Done
ZStd b
If you trace the graph above, x values start at 0
and increment by .1587301587.
ZInt b
If you trace this graph, x values increment
by 1.
