P.218 Incorporating Recursion Table & Graph functions in a program lets you generate
numeric tables and perform graphing operations. The following shows various
types of syntax you need to use when programming with Recursion Table & Graph
functions.
• Recursion formula input

Type_ .... Specifies recursion type.
”3 a
