Step?
Input the increment step (Default = 1).
Note: The Step specifies by how much the Start
value should be sequentially incremented as the
number table is generated. If you specify Start = 1
and Step = 1, X sequentially will be assigned the
values 1, 2, 3, 4, and so on to generate the number
table until the End value is reached.
• Inputting the Step value and pressing generates and displays the
number table in accordance with the parameters you specified.
• Pressing while the number table screen is displayed will return to
the function input screen in step 2.

Note: • You can use the number table screen for viewing values only. Table
contents cannot be edited. • The number table generation operation causes
the contents of variable X to be changed.
Important: The function you input for number table generation is deleted
whenever you display the setup menu in the TABLE Mode and switch between
Natural Display and Linear Display.
Inequality Calculations (INEQ)
(fx-95ES PLUS only)
You can use the following procedure to solve a quadratic inequality or cubic
inequality.
1. Press (INEQ) to enter the INEQ Mode.
2. On the menu that appears, select an inequality type.
To select this inequality type: Press this key:
Quadratic inequality
(aX
2
+ bX + c )
Cubic inequality
(aX
3
+ bX
2
+ cX + d )
3. On the menu that appears, use keys through to select the inequality
symbol type and orientation.
4. Use the Coefficient Editor that appears to input coefficient values.
• To solve
x
2
+ 2x – 3 < 0, for example, input the coefficients a = 1, b = 2,
c = –3 by pressing 1 2 3 .
• To change a coefficient value you already have input, move the cursor
to the appropriate cell, input the new value, and then press .
• Pressing will clear all of the coefficients to zero.
