program.

2. Place the cursor on the point where you want to begin drawing. Press Í to turn
on the pen.

at a time.
4. Press Í to turn off the pen.

selected function.
Note: To continue drawing on the graph, move the
cursor to a new position where you want to begin
drawing again, and then repeat steps 2, 3, and 4. To
