Algebraic Long Division

This interactive file shows how cubic polynomials can be divided by linear factors. The first four interactive sheets generate cubic expressions and the steps in the algebraic long division method can be gradually revealed. The constant term in the cubic can be altered...

Circles

This Excel file has a series of sheets which illustrate the link between the equation of a circle and the corresponding graph. It goes on to deal with the intersection of a circle with a straight line.

The first...

Functions

Composite Functions
The first five sheets all have a similar format. A number is operated on by...

Ellipse

This program deals with various aspects of the coordinate geometry of an ellipse. The first two sheets show the connection between ellipse and the auxiliary circle and also the focus/directrix definition of the ellipse. Subsequent sheets trace an interesting loci...
