Defining the Expression
In this step, you specify coefficients and define the expression. You can select any of the
three following methods for specifying coefficients.
• {
RAND
} ... {random generation of coefficients}
• {
INPUT
} ... {key input of coefficients}
• {
SMPL
} ... {selection of coefficients from samples}
• {
SEED
} ... {selection of a number from 1 to 99 (specification of the same number
displays the same expression)}
1
(RAND) or
w
generates random coefficients and defines the expression.
2
(INPUT) displays the coefficient input screen. Input coefficients, pressing
w
after each.
After you finish inputting all the coefficients, press
6
(EXE) to define the coefficient.
3
(SMPL) displays a number of preset sample expressions. Highlight the one you want to
use and then press
w
to define it.
Pressing
4
(SEED) displays a number selection screen. When you want to create the same
problem on another calculator, specify an appropriate matching number and press
w
.
No matter what method you use, the expression you define is displayed in the output area.
You can copy an expression to the Graph Mode as a graph function*
1
.
• {
L
•
COP
}
/
{
R
•
COP
} ... copy {left side element}/{right side element} as a graph function
(Simultaneous Equation Mode*
2
)
• {
1
•
COP
}
/
{
2
•
COP
} ... copy {first}/{second} expression as a graph function

1
In the case of an inequality, the inequality
symbols are also copied.
*
2
Simultaneous equations are transformed to the
format Y = AX + B when copied.
