Example 2

Draw a graph of

Use the same View Window parameters as those provided in

Example 1.

• To input a different recursion formula after a graph is drawn, press ! Q.

This displays the Recursion Menu where you can input a new formula.

k k k k k Drawing a Convergence/Divergence Graph (WEB graph)

With this feature, you can draw a graph of

terms of linear recursion between two terms, substituted respectively for

the function

(

). The resulting graph can then be viewed to determine whether

or not the graph is convergent or divergent.

Example 1

To determine whether or not the recursion formula

+ 3

is convergent or divergent.

Use the following table range.

Start = 0

= 0.01

= 0.11

Use the following View Window parameters.

Xmin

Xmax = 1

Xscale = 1

This example assumes that the following two recursion formulas are already

stored in memory.
