Specifying the Graph Type
Before you can store a graph function in memory, you must first specify its graph
type.
1. While the Graph Function Menu is on the display, press
3
(TYPE) to display
the graph type menu, which contains the following items.
• {
Y=
}
/
{
r=
}

{
Parm

{
X=c
} ... {rectangular coordinate}/{polar coordinate}/
{parametric}/{X=constant} graph
• {

• You will not be able to store the expression in an area that already contains a
parametric function. Select another area to store your expression or delete the
existing parametric function first. This also applies when storing
r
