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

+ bX + c )

Cubic inequality

(aX

+ bX

+ 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

+ 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.
