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.

To generate a number table for the function f(x) = x2 +

1

for the

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

(aX2

+ bX + c )

Cubic inequality

(aX3

+ bX2 + 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 x2 + 2x – 3 < 0, for example, input the coefficients a = 1, b = 2, c = –3 by pressing 12  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.
