Notes on the maths used in the applet:

The line to be plotted is specfied in the form y = ax^n + bx^m... This line is plotted on the graph and begins to rotate. It volume can be found using the formula for the volume of a circle, which is PI*r^2. The area of each point on the axis as it rotates can be found using this, and the volume is then the sum of all of these areas. The volume then, can be found using the formula
