8. Entering Functions

• To enter functions, press
expressions (an equation must be entered to display a graph).
• This calculator supports a total of four coordinate systems for the graphing function.
(X-Y, parametric, polar, sequence — SET UP menu)
• The input screen and number of functions that can be stored in memory varies
depending on the mode. (One of the following screens appears when
pressed.)
X-Y
Memory capacity: 10 equations
To set to the sequential graphing mode. (Graphs are drawn one at
a time, in order.)
To set to the simultaneous graphing mode. (Two or more graphs
are drawn at the same time.)
Set to the COB-Web graph plot mode.
To set u( n –1) to the X axis, and u( n ) to the Y axis.
To set n to the X axis, and u( n ), v( n ) and w( n ) to the Y axis.
To set u( n ) to the X axis, and v( n ) to the Y axis.
To set u( n ) to the X axis, and w( n ) to the Y axis.
To set v( n ) to the X axis, and w( n ) to the Y axis.
to display the function input screen, then enter
