3(POINTS) ... Select to input the coordinates of three points on a plane.
• Inputting a coefficient that matches any of the conditions below will cause an “Invalid Setting”
error.
• EXPRESS: a=0 and b=0 and c=0
• VECTOR:
• Both the u vector and v vector coefficient, or either the u vector or v vector coefficient is
0.
• u vector and v vector are the same direction.
• POINTS:
• Two of the three points are the same value.
• The three points are on a straight line.
