# 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.
