Inequalities in GeoGebra
We can visualize an inequality of two variables on GeoGebra. For example, you can type the linear inequality in GeoGebra below.
But GeoGebra does not have a powerful computation engine like Mathematica. It has its limitations - it cannot visualize complicated inequalities like .
Classwork: Besides linear inequalities, find out what other types of inequalities of two variables can be visualized in GeoGebra.
The types of inequalities of two variables that can be visualized are ....
The following is a GeoGebra applet about a linear programming problem.
