Selecting The Solution Analysis Method - Sharp EL-9650 Operation Manual

4. To find the solution:
Press ≤ to move the cursor to "C=" (after
Ï
inputting numerical values, the cursor pointer is at
"D").
Press and
shown to the right.
* After the solution has been found, press
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
equation input screen, allowing you to correct or edit the previously input equation.

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
Ï
the Newton method.
• To select the analysis method:
