Exploring the graph
The menu button gives you access to the following common tools for exploring plots:
—Displays a range of zoom options. (The and keys can also be used to zoom
in and out.)
—When active, enables a tracing cursor to be moved along the contour of the plot (with the
coordinates of the cursor displayed at the bottom of the screen).
—Specify a T value and the cursor moves to the corresponding x and y coordinates.
—Display the functions responsible for the plot.
These tools are common Plot view operations.
Typically, you would modify a plot by changing its denition in Symbolic view. However, you can modify some
plots by changing the Plot Setup parameters. For example, you can plot a triangle instead of a circle simply by
changing two plot setup parameters. The denitions in Symbolic view remain unchanged. To do this, use the
following procedure.
1.
Press .
2. Change T Step to 120.
