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 @hat 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 Zand use the cursor for defining the box area.
