To Store An X = Constant Expression; To Store An Inequality; To Create A Composite Function - Casio fx-9860G Series User Manual

To store an X = constant expression *

Example To store the following expression in memory area X4 : X = 3
3(TYPE)4(X=c) (Specifi es X = constant expression.)
d(Inputs expression.)
w(Stores expression.)
• Inputting X, Y, T, r, or θ for the constant in the above procedures causes an error.

To store an inequality *

To store the following inequality in memory area Y5 : y > x
Example
3(TYPE)6( )1(Y>) (Specifi es an inequality.)
vx-cv-g(Inputs expression.)
w(Stores expression.)

To create a composite function

Example To use relations in Y1 and Y2 to create composite functions for Y3
and Y4
Y1 = (X + 1), Y2 = X
Assign Y1 ° Y2 to Y3, and Y2 ° Y1 to Y4.
(Y1 ° Y2 = ((x
Input relations into Y3 and Y4.
3(TYPE)1(Y=)
1(Y)b(1(Y)c)w
4(GRPH)1(Y)c
(1(Y)b)w
• A composite function can consist of up to fi ve functions.
