Inputting a Recursion Formula and Generating a Table
4. Display the table of the recursion formula. At this time, a menu of table
functions appears at the bottom of the screen.

• Note the following points when specifying a table range.
• If a negative value is specified as a start or end value, the calculator
drops the negative sign. If a decimal value or fraction is specified, the unit
uses only the integer part of the value.
• If the value of

• If the start value is greater than the end value, the calculator swaps the
two values before generating the table.
• If the start value is the same as the end value, the calculator generates a
table using the start value of variable
• If the start value is very large, it may take a long time to generate a table
for linear recursion between two terms and linear recursion between
three terms.
• Changing the angle unit setting while a table generated from a trigonometric
expression is on the display does not cause the displayed values to change.
To cause the values in the table to be updated using the new setting, display
the table, press 1 (FORM), change the angle unit setting, and then press
6 (TABL).
