Julia and Mandelbrot Set Explorer

David E. Joyce

For background on Julia and Mandelbrot sets, see the introduction. There is detailed help available for using this form. For more information on complex numbers, see Dave's Short Course on Complex Numbers. Also, check out the Applet to explore the Mandelbrot set.

I recently stumbled upon StumbleUpon that helps you discover and share great websites. You can create a public blog of websites you like and find other websites like those you like. You'll need either a Firefox browswer or a Mozilla 1.5-1.8 complient browser.
