= 3
b
n
+ 0.2 is divergent.
• Inputting
b

for the expression
a

, or Inputting
a
n
or

for the expression
b
n

To draw a recursion formula graph using Dual Screen
Selecting “T+G” for the Dual Screen item of the Set Up Screen makes it possible to
display both the graph and its numerical table of values.
Example
To draw the graph of
a
n

(T+G)
(Specifies T+G for Dual Screen.)
J6
(TABL)
(Draws the graph and shows the table.)
6
(G•PLT)
(Draws plot type graph.)
• Pressing
!6
(G
↔
T) causes the graph on the left side of the Dual Screen to
fill the entire display. Note that you cannot use the sketch function while a graph
is displayed using
!6
(G
