(TABL)
(PHAS)
If you enter three expressions on the RECUR mode screen and select all of them for table
creation, you will need to specify which two of the three expressions you want to use to draw
the phase plot. To do so, use the function menu that appears when you press (PHAS) on
the table screen.
(
ab)..........Graph using a
n
(a
n
+1
, a
n
+2
) and b
n
(b
n
+1
, b
n
+2
).
(
bc)..........Graph using b
n
(b
n
+1
, b
n
+2
) and c
n
(c
n
+1
, c
n
+2
).
(
ac)..........Graph using a
n
(a
n
+1
, a
n
+2
) and c
n
(c
n
+1
, c
n
+2
).
Specifying “On” for the “3Display” of the Setup screen causes the sum of each term to be
included in the table. At this time you can select use of the two numeric sequences as-is to
draw the plot graph, or use of the sums of each of the two numeric sequences. To do so, use
the function menu that appears when you press (PHAS) on the table screen.
(
a
n
) ............Use numeric sequence for graphing.
(3
a
n
)..........Use numeric sequence sums for graphing.
When “On” is selected “3Display” on the Setup screen and all three of the expressions
you input in the RECUR mode are selected for table creation, use the function menu
that appears when you press (PHAS) on the table screen to specify which two of the
expressions you want to use, and to specify whether you want to use numeric sequence
data or numeric sequence sum data.
