Settings Tab

Use the Settings tab to:

• change the scales of the x- and y-axes
• change spacing between the tick marks on the x- and y-axes
• change the x-values in the Function Table

Axes

The standard viewing window displays a scale along the x- and the y-axes from a minimum (Min) of -10 to a maximum (Max) of 10. In the standard window, tick marks are 1 unit apart.

To change these values, enter new numbers. Click Graph to apply the changes.

Table Settings

Use Table Settings to set the ten values of x listed in the Function Values table.

The default settings have the x-values start at -5 and increase by 1s.

These values can be changed. For example, if the Start value is -25 and the Step is 5, the ten values of x in the table will be the values between -25 and 20: -25, -20, -15, -10, etc.

After changing the table settings, click Graph to apply the changes.

Coordinate System

There are three special coordinate systems available.

Standard Window

Clicking Standard Window returns to the default settings:

• x- and y-axes show values from -10 to 10, and
• tick marks are 1 unit apart.

Square Window

In many windows, including the Standard Window, the units on the two axes are different sizes, so graphs are distorted.

Clicking "Square" changes the y-axis settings so units along the two axes have the same length.

In the "Square" setting, the user can only change x-axis settings. The y-axis settings change automatically to keep the units the same length.

Integer Window

The Integer setting changes the x-scale so trace points always have integer x-values. (Note: The Trace function is in the Equations tab.)

In the "Integer" setting, the user cannot change any axis settings.

Whenever the coordinate system changes, click Graph to apply the changes.
