Chapter 10: The SOLVER Feature
Graphic method
The Graphic method is another way of approximating solutions,
using graphical representations. This method is particularly useful
when finding more than one solution on a graph axis.
Example
Obtain values for "Y = X
1. Press @ ' to enter SOLVER. Clear screen entries by
2. Enter "Y = X
3. In the next window, set the Y
Note:
Unlike in the Newton&bisection
method, the X value will not be
assumed as the starting point for
the Graphic method.
