SOLVER FUNCTION
*
If multiple solutions exist:
• When the first solution is obtained, the process is
stopped. If other solutions exist, change the param-
eters to perform the process in a different range.
• It is possible to change the initial value (START) for
the Newton method and the range (BEGIN and END) for the graph method, respec-
tively.
• Additionally, if more than one intersection exists on the graph screen, the CALC
function can be used.
• To find the second intersection in the above example, follow these steps.
1. Press
Ï˘
.
2. As a result, “T = 1.675379859 (
1.68 sec.)” is obtained.
3. Registering an Equation
To register an equation, input the equation after entering the SOLVER mode or enter
one of the screens after executing calculation.
• An equation which is frequently used can be registered using the following steps .
• Registration of solver equations is done while in the
SOLVER mode.
1. Press
Ï
to display the solver menu.
2. Press
C
®
to select the registration mode
(SAVE).
3. Input an equation name.
The number of characters for the equation name is 8
or less.
When in the SAVE mode, ALPHA LOCK is automatically placed so that letters may
be entered without having to press
Å
