Applet to investigate whether a given function is continuous at a point or uniformly continuous (part of the Interactive Real Analysis project).

• Click on Options to bring up a dialog window for options
• Click on the graph to set the point where continuity is checked

Continuity applied to this applet means: A function is continuous if for any given epsilon you can find a corresponding delta such that the red area always touches the graph inside the green area.
