To Store An Inequality; To Create A Composite Function - Casio fx-9860G AU User Manual

u To store an X = constant expression *
Example To store the following expression in memory area X4 :
X = 3
3(TYPE)4(X=c) (Specifies X = constant expression.)
d(Inputs expression.)
w(Stores expression.)
, or θ for the constant in the above procedures causes an error.

u To store an inequality *
Example To store the following inequality in memory area Y5 :
y x
> 2
3(TYPE)6(g)1(Y>) (Specifies an inequality.)
vx-cv-g(Inputs expression.)
w(Stores expression.)
u 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.

• A composite function can consist of up to five functions.
