Aplets and their views 2-15
– moves the leftmost cursor to the
screen’s left edge and moves the
rightmost cursor to the screen’s right edge.
– The menu key copies the right plot to the left
plot.
3. To un-split the screen, press . The left side takes
over the whole screen.
The Plot-Table view gives you two simultaneous views of
the plot.
1. Press . Select
Plot-Table and
press . The screen
displays the plot on the
left side and a table of
numbers on the right side.
2. To move up and down the table, use the and
cursor keys. These keys move the tra.ce point left or
right along the plot, and in the table, the
corresponding values are highlighted.
3. To move between functions, use the and
cursor keys to move the cursor from one graph to
another.
4. To return to a full Numeric (or Plot) view, press
(or ).
Overlay plots If you want to plot over an existing plot without erasing
that plot, then use Overlay Plot instead of
. Note that tracing follows only the current
functions from the current aplet.
Decimal scaling Decimal scaling is the default scaling. If you have
changed the scaling to Trig or Integer, you can change it
back with Decimal.
Integer scaling Integer scaling compresses the axes so that each pixel is
and the origin is near the screen center.
Trigonometric
scaling
Use trigonometric scaling whenever you are plotting an
expression that includes trigonometric functions.
Trigonometric plots are more likely to intersect the axis at
points factored by π.
