User guide

A standard viewing window is commonly used in mathematics. The dimen-
sions are [−10, 10, 1] by [−10, 10, 1]. This means Xmin and Ymin are −10,
xmax and ymax are 10 and increments of 1 are used on both axes. To choose
a standard viewing window use Zoom from the menu bar followed by Quick
Standard.
The values Xmin, Xmax, Xscale, Ymin, Ymax, and Yscale may be changed
by using 6 found in the tool bar. Note that the values have changed to
[−10, 10, 1] by [−10, 10, 1] as mentioned earlier. Other options like dot and
tmin will not changed for the scope of this manual.
The tool bar option marked ! may be used or r will create a split
screen. From the y= window you may change the style of the each graph.
Tap the line segment located to the right of the equation.
