• Certain View Window parameters can produce errors in graph analysis result
values.
• The message ”Not Found” appears on the display when graph analysis is
unable to produce a result.
• The following can result in inaccurate analysis results or may even make it
impossible to obtain a solution at all.
• When the solution is tangent to the
x-axis.
• When the solution is a point of tangency between two graphs.
