View Window parameter precaution
• An error occurs if you input 0 for t θ step.
• An error also occurs if you input a value that is out of range for a parameter, if you input a
minus sign only, or if you perform any other illegal input.
• An error occurs if ymin is greater than or equal to the ymax. The same is also true for the
xmin and xmax. If the value you specify for t θ min is greater than the value you specify for
t θ max, the t θ step setting is automatically changed to a negative value.
• When the View Window setting produces an axis that does not fit on the display, the scale
of the axis is indicated on the edge of the display closest to the origin.
• Changing the xmin (ymin) or xmax (ymax) value automatically changes the xdot (ydot)
value, while changing the xdot (ydot) value automatically changes the xmax (ymax) value.
To initialize View Window parameter
(1) On the application menu, tap
(2) Tap
. This displays the View Window dialog box.
(3) Tap [Memory] and then [Initial]. This initializes View Window parameters to the values
noted below.
xmin = –7.7
xmax = 7.7
ymin = –3.8
ymax = 3.8
t θ min = 0
t θ max = 6.28318530717 t θ step = 0.05235987755
To initialize the View Window for an angle unit
(1) On the application menu, tap
(2) Tap
. This displays the View Window dialog box.
(3) Tap [Memory] and then [Trigonometric]. This initializes View Window parameters in
accordance with the angle unit, as shown below.
(Setup: Radian)
xmin = –9.4247779607
xscale = 1.57079632679
ymin = –1.6
yscale = 0.5
t θ min = 0
t θ step = 0.05235987755
(Setup: Degree)
xmin = –540
xmax = 540
ymin = –1.6
ymax = 1.6
t θ min = 0
t θ max = 360 t θ step = 3
