u To save data in Dynamic Graph memory
1. While a Dynamic Graph draw operation is being performed, press A to change to the
speed adjustment menu.
2. Press 5(STORE). In response to the confirmation dialog that appears, press 1(Yes) to
save the data.
u To recall data from Dynamic Graph memory
1. Display the Dynamic Graph relation list.
2. Pressing 6(RECALL) recalls Dynamic Graph memory contents and draws the graph.
10. Graphing a Recursion Formula
k Generating a Number Table from a Recursion Formula
You can input up to three of the following types of recursion formulas and generate a number
table.
• General term of sequence {
a
n
}, composed of a
n
, n
• Linear two-term recursion composed of a
n
+1
, a
n
, n
• Linear three-term recursion composed of a
n
+2
, a
n
+1
, a
n
, n
1. From the Main Menu, enter the Recursion mode.
2. Specify the recursion type.
3(TYPE) 1(
a
n
) ... {general term of sequence a
n
}
2(a
n
+1
) ... {linear two-term recursion}
3(a
n
+2
) ... {linear three-term recursion}
3. Input the recursion formula.
4. Specify the table range. Specify a start point and end point for
n . If necessary, specify a
value for the initial term, and a pointer start point value if you plan to graph the formula.
5. Display the recursion formula number table.
