Casio fx-9750G Recursion Table and Graph - Manual (Page 5)

253
The table range settings specify the conditions that control the value of variable n in
the recursion formula, and the initial term of the numeric value table.
Start ................ Starting value of variable n
End ................. Ending value of variable n

, a

.......... Values of 0th term a

/ b

, 1st term a

.
• The value of variable n increments by 1.
3. Specify the range of the table.

4. Display the table of the recursion formula. At this time, a menu of table functions
appears at the bottom of the screen.
J6 (TABL)
• There can be only one recursion table stored in memory at one time.
• Except for linear expression n , any of the following can be input for general
term { a
n
} to generate a table: exponential expressions (such as a
n
= 2 n – 1),
fractional expressions (such as a
n
= ( n + 1)/ n ), irrational expressions (such as
a
n
= n – ), trigonometric expressions (such as a
n
= sin 2 n
π
). n – 1
• 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 a
0
/ b
0
(or a
1
/ b
1
) is greater than the start value, the calculator
makes the starting value of variable x the same as the value of a
0
/ b
0
(or a
1
/
b
1
) before generating the table.
• 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 x only.
• 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.
