You can use the following procedure in the EQN mode to solve

simultaneous linear equations with two or three unknowns.

1. Press [ MODE ] [3] [1] or [ MODE ] [3] [2].

2. Enter the value for each coefficient (a

, etc.) and press [ = ].

 To change a coefficient value you already have input, move

the cursor to the appropriate cell, input the new value, and

then press [ = ].

 To clear all the coefficients, press [ AC ].

(Note) : After inputting data, press [ = ]. The registers the value

and displays up to six of its digits in the currently

selected cell.

3. When all coefficients have been entered, press [ = ] to solve the

equation.

4. Each press of [ = ] displays the next solution.

5. Pressing [ = ] while the final solution is displayed returns to the

coefficient entry display.

(Note) : Pressing [ AC ] while a solutions is displayed will return

to the coefficient entry display.

Function Table

Use TABLE ( [ MODE ] 4 ( TABLE ) ) mode for generation of a

function table.

TABLE mode lets you define a function and express it in a tabular

form. To set up a function table, you need to: (See Example 52.)

1. Press [ MODE ] [4] (TABLE)

2. Enter a function, and press [ = ]

3. Input the Start, End, and Step value of X, and press [ = ]

4. After Step 3, a table of values that consists of each input, X, and

its corresponding output, f(X), is generated.

(Note) : 1. Only the variable X is available to be used in a

function.

2. The Start, End, and Step value you specify should

produce a table not exceed a maximum of 30 X-values.

Using Verify

Use VERIF ( [ MODE ] 5 ( VERIF ) ) mode for compare of two values.

(See Example 53)

You can enter the following expressions for check mode VERIFY.

1) Equalities or inequalities involving a relational operator

4 = √16; 4 ≠ 3; π > 3; 1+2 ≦ 5; (3x6) < (2+6)x2; etc.

2) Equalities or inequalities involving multiple relational operator

≦

1 < 1+1; 3 <

< 4; 2

= 2+2 = 4; 2+2 = 4 < 6; 2+3 = 5 ≠

2+5 = 8; etc.

Pressing the [2nd][VERIFY] key displays a menu of functions. Press

the number key that corresponds to the function you want to input.
