SOLVER FUNCTION

2. Selecting the Solution Analysis Method

• The calculator has three kinds of analysis methods that may be used to find the

solution. They are equation, Newton, and graph methods.

• When the solution can be found by a simple algebraic equation, the equation

method is normally used. The calculator automatically selects this method in the

default setting (unless otherwise specified).

• If the solution cannot be found by the equation method, it automatically switches to

the Newton method.

• To select the analysis method:

Press

to enter the solver mode and press

again. The following

menu will appear on the screen.

4. To find the solution:

Press

≤

to move the cursor to “C=” (after

inputting numerical values, the cursor pointer is at

“D”).

Press

and

to display the answer screen

shown to the right.

After the solution has been found, press

to return to the variable input screen. On this

screen, you may change the numeric values in the variables and select another unknown
variable to find the solution again.

To edit the equation, press

on the variable input screen to change the screen to the

equation input screen, allowing you to correct or edit the previously input equation.

The following analysis methods are built into the menu, [A METHOD].

[1 Equation] :

Solution is directly found by the equation method.

[2 Newton] :

Solution is found by the Newton method.

[3 Graphic] :

Solution is found by the graph method.
