Registering An Equation - Sharp EL-9650 Operation Manual

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
Ï˘
function can be used.
• To find the second intersection in the above example, follow these steps.
1. Press
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 .
