Rectangle Given by a Corner


  You will need to enable Java in order to use this demonstration.  

Please be patient while the applet is loaded (93K)...

Interaction Controls

Click on the "NEW DEMO" button at the left to start the demonstation. It may take a few moments to open the windows needed for this applet. You should eventually get two new windows: the "Controls" window and the "Graph" window. Move the windows so you can see them both.

A rectangular region with horizontal and vertical sides and one corner at the origin is an example of a two-dimensional object. We can determine any such region by giving the coordinates (c,d) of the point farthest from the origin.

Use the values in the "Controls" window to change the coordinates of the upper right-hand corner. The < and > buttons decrease or increase the values of the associated variables.

When you are done with the demonstration, choose the "Exit Demo" menu item from the "Windows" menu of the "Controls" window. The applet will not exit until you do so.

Mathematics Awareness Month is sponsored each year by the Joint Policy Board for Mathematics to recognize the importance of mathematics through written materials and an accompanying poster that highlight mathematical developments and applications in a particular area.
