Example: To draw a line tangent to the graph y = x

2
x – 2.
(2) Tap $ to graph the function.
(3) Tap [Analysis], [Sketch], and then [Tangent].
This displays the crosshair pointer along with its corresponding coordinate values.
(4) Press 1.

of tangency x-value, with 1 specified as the point.
3-6-3
Using the Sketch Menu
(5) Tap [OK].
This closes the dialog box and moves pointer to the location you specified in step (4).
(6) Press E.
Tip
Instead of inputting coordinate values in steps (4) and (5), you can use the cursor key or the
graph controller arrows to move the pointer to the point of tangency on the Graph window.
u To draw a line that is normal to a graph
The procedure for drawing a line that is normal to a graph is virtually identical to the
procedure “To draw a line tangent to a graph”, above. The only difference is in step (3),
where you need to tap [Analysis], [Sketch], and then [Normal] instead of [Tangent].
