u To store an X = constant expression *

1

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.

u To store an inequality *

1

Example

To store the following inequality in memory area Y5 :

y > x

2

− 2

x − 6

3(TYPE)6(g)1(Y>) (Specifi es 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

2

+ 3

Assign

Y1

°Y2 to Y3, and Y2 °Y1 to Y4.

(Y1

°Y2 = ((x

2

+ 3) +1 ) = (x

2

+ 4) Y2 °Y1 = ( (X + 1))

2

+ 3 = X + 4 (X > −1))

Input relations into Y3 and Y4.

3(TYPE)1(Y=)J4(GRPH)
1(Y)b(1(Y)c)w
J4(GRPH)1(Y)c
(1(Y)b)w

• A composite function can consist of up to fi ve functions.

A function cannot be stored into a memory

area that already contains a function of a
different type from the one you are trying to
store. Select a memory area that contains a

function that is the same type as the one you are
storing, or delete the function in the memory area to
which you are trying to store.
