Java Applet Worksheet 2

Level Curves

(Written by Dr. Steve Harris)

 

To access Professor May's applets (based on work of Tom Banchoff):

          http://www.slu.edu/classes/maymk/MathApplets-SLU.html
 
       
  link: Level Curve
         
button: Level Curve Applet

Spread the graphs out where you can see them all, as well as the control panel.

Use the Level Curve Applet to investigate the function

 

f(x, y) = - x2y2 + x2 + y2

 

At what z-values does the contour curve change abruptly?

What is the nature of the change?

What is this telling you about the shape of the surface?
