Inequality Calculations (Ineq); (Fx-95Es Plus Only) - Casio FX-350ES PLUS User Manual

Step?
• Inputting the Step value and pressing
number table in accordance with the parameters you specified.
• Pressing
the function input screen in step 2.
To generate a number table for the function
range –1

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)

You can use the following procedure to solve a quadratic inequality or cubic
inequality.
1. Press
2. On the menu that appears, select an inequality type.
To select this inequality type:
Quadratic inequality
Cubic inequality
3. On the menu that appears, use keys
symbol type and orientation.
4. Use the Coefficient Editor that appears to input coefficient values.

• To solve
c
= –3 by pressing 1
• To change a coefficient value you already have input, move the cursor
to the appropriate cell, input the new value, and then press
• Pressing
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.
