#Certain V-Window parameters can produce errors in values produced as graph analysis results.

#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.
