u To standardize the View Window

(1)On the application menu, tap T.

(2)Tap 6. This displays the View Window dialog box.

(3)Tap [Memory] and then [Standard]. This applies the standard View Window parameters shown below.

xmin = –10

xmax = 10

xscale = 1

xdot = 0.12987012987

ymin = –10

ymax = 10

yscale = 1

ydot = 0.26315789473

tθ min = 0

tθ max= 6.28318530717

tθ step = 0.05235987755

u To auto configure View Window parameters

(1)On the application menu, tap T.

(2)Tap 6. This displays the View Window dialog box.

(3)Tap [Memory] and then [Undefined]. This causes View Window parameters to be configured automatically in accordance with the function on the Graph Editor window.

•When multiple expressions are selected for graphing, the one with the lowest numbered line is used for auto setting of View Window parameters.

Tip

•Initializing or standardizing View Window parameters causes polar/parametric coordinate values tθ min, tθ max, and tθ step to be adjusted automatically in accordance with the currently selected angle unit. In the Degree mode, for example, the following settings are configured:

tθ min = 0, tθ max = 360, tθ step = 3

kUsing View Window Memory

You can store your custom View Window settings for later use.

u To save the current View Window setup

(1)On the application menu, tap T.

(2)Tap 6.

(3)On the View Window dialog box, configure the parameters you want.
