k Initializing and Standardizing the V-Window
u To initialize the V-Window
1. From the Main Menu, enter the GRAPH mode.
2. Press !3(V-WIN).
This displays the V-Window setting screen.
3. Press 1 (INIT) to initialize the V-Window.

u To initialize the V-Window in accordance with an angle unit
In step 3 of the procedure under “To initialize the V-Window” above, press 2(TRIG) to
initialize the V-Window in accordance with an angle unit.
Xmin = –3π (rad), Xmax = 3π (rad), Xscale = π /2 (rad), Xdot = π /21 (rad),
Ymin = –1.6, Ymax = 1.6, Yscale = 0.5
u To standardize the V-Window
The following are the standard V-Window settings of this calculator.
Xmin = –10, Xmax = 10, Xscale = 1, Xdot = 0.15873015
Ymin = –10, Ymax = 10, Yscale = 1

In step 3 of the procedure under “To initialize the V-Window” above, press 3(STD) to
standardize V-Window settings in accordance with the above.
