This applet visualises the Mandelbrot set onto a complex plane.
[Def. Mandelbrot set]
The Mandelbrot set M consists of all of those (complex)
cvalues for which the corresponding orbit of 0 under
z^2 + c does not escape to infinity.
Although it is not possible to determine if certain cvalues
lies in the Mandelbrot set, as the number of iteration increases
(to infinite), the closer boundary of M can be plotted.
[For more technical
information about the available parameters, click here.]
Most parameters are selfexplanatory and you can
always see brief description of each parameter by moving the mouse
pointer over the wizard.

First of all, define the "Width"
and "Height" of the applet area and select
a value for "Resolution." Resolution is the
magnification rate of the internal image size. 
For example, the value 3 gives three times
as big image size as the internal image has. So, it works
as a zooming parameter.
As for colouring of the boundary of M,
27 palettes are available. Choose a palette number and explore
the result.


Look at the bottom of the left picture. Determine
"StartX" and "StartY" values.
These are the initial values with which recursive calculation
of z(n+1)=z(n)^2 + c (z=x+yi) begins.
Xmin and Ymax determine normal
XY complex plane scrolling values, while Xmax and Y
min give XY magnification rate.
