Chapter 12: The SOLVER Feature
Note:
The analysis will be limited to the range specified; a solution
outside of the analysis range will not be detected. If no crossing
point is found in the range, then a message “No solution found”
will show at the bottom of the screen.
7. Pressing
@ h at this point will engage the analysis,
as well as the graphical representation of the equation. Note
that while the cursor flashes at the upper right corners of the
screen, the calculator is busy processing tasks.
8. When the processing is
complete, you will get the
first value of X (the small-
est), with a flashing star on
the graph at the crossing
point.
To obtain the next X value,
press
@ k.
Note:
To enlarge a part of graph after
the solution has been found,
you may use the ZOOM Box
function. Press
Z and use the cursor for defining the box
area.
