5-3 Drawing a Graph

You can store up to 20 functions in memory. Functions in memory can be edited, recalled,
and graphed.
k k k k k 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 list is on the display, press 6(g)3(TYPE) to display the
graph type menu, which contains the following items.
• {Y=}/{r=}/{Param}/{X=c} ... {rectangular coordinate}/{polar coordinate}/{parametric}/
{X=constant}*
• {INEQUA}
• {Y>}/{Y<}/{Yt t t t t }/{Ys s s s s } ... {Y>f(
• {CONV}
Y=}/{
• {
'
2. Press the number key that corresponds to the graph type you want to specify.

u To store a rectangular coordinate function (Y =) *
Example To store the following expression in memory area Y1 :
3(TYPE)b(Y =) (Specifies rectangular coordinate expression.)
cvx-f(Inputs expression.)
w (Stores expression.)
u To store a polar coordinate function (
Example To store the following expression in memory area

area that contains a function that is the same type
as the one you are storing, or delete the function in
the memory area to which you are trying to store.
