Set Window Dimensions


While viewing a graph, press to see the window used to graph a function.


X
min establishes the smallest x value, the left end of the x-axis.
max establishes the largest x value, the right end of the x-axis.
This value must be larger than the value entered for min.
scale defines the spacing between tic marks along the x-axis.
To turn off the marks, set it to 0.

Y
min establishes the smallest y value, the bottom of the y-axis.
max establishes the largest y value, the top of the y-axis.
This value must be larger than the value entered for min.
scale defines the spacing between tic marks along the y-axis.
To turn off the marks, set it to 0.

T,theta
max establishes the starting value for parametric and polar equations.
min establishes the ending value.
This value must be larger than the value entered for min.
pitch defines the step used between succesive values evaluated.


To change a setting, select that value using the cursor keys and type the desired value and .

To store a set of window settings, press to select Zoom Store followed by the appropriate menu key.
To recall an already stored set, press to select Zoom Recall followed by the appropriate menu key.

Some predefined settings can be accessed here as well.

Press for the initial window:



Press for the trig window:



Press for the standard window:



For some other predefined settings see the zoom options.


Note: The exact values the Zoom Trig option gives depends on the angle mode you're in. The x values will range from one and a half revolutions from both sides of the origin, the y values from -1.6 to 1.6.

For example, in degree mode it gives:



where in radian mode it gives:
