Some sketch functions require specification of two points. After you press U to specify the
first point, use the cursor keys to move the pointer to the location of the second point and
press U.
• You can specify line type for the following sketch functions: Tangent, Normal, Inverse, Line,
F
• Line, Circle, Vertical, Horizontal, Pen
Example Draw a line that is tangent to point (2, 0) on the graph for
y = x (x + 2)
(x – 2).
