uTo 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.

uTo 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 FormulakGenerating 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 {an}, composed of an, n

•Linear two-term recursion composed of an+1, an, n

•Linear three-term recursion composed of an+2, an+1, an, n

1. From the Main Menu, enter the Recursion mode.

2. Specify the recursion type.

3(TYPE)1(an) ... {general term of sequence an} 2(an+1) ... {linear two-term recursion} 3(an+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.
