a circle of radius 3 center at the origin.
A solid circle will be used because the inequality is not strict.
\Use two test points, one inside the circle, the other out side.
\In side (0, 0): ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=56bc699bba0666b3d77eb67fe0ea1679.png\")
Belong to the graph.
Out side (4, 0): ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=e1f33ef89aae39252123a7e55ad87f3e.png\")
Does not belong to the graph.![\"\"](\"/userfiles/image/steps_images/step2.JPG\")
All the points inside and on the circle satisfy the inequality.
