GeoGebra Tutorial: How to change the x-interval to pi or pi/2

In graphing Trigonometric Functions, there are cases that you need to change the interval of the x-axis in terms of π.  In this tutorial, you will learn how to change the interval of the x-axis. 

1.) Right click a blank space on the Graphics view and then click on Graphics... from the pop-up menu to display the Preferences dialog box.

2.) In the Preferences dialog box, click on the xAxis tab, and then check the Distance check box.

3.) In the drop-down list box at the right of the Distance check box, select π or π/2 and then click the Close button to close the dialog box.

After step 3, the interval of the x-axis should be π or π/2.
