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...

Hyperbola

This program begins with graphs of the hyperbola in the form x2/a...

Inverse Functions

Inverse Functions. Linear
This file starts with an example of how to find the inverse of a linear function. New examples can be generated and the graphs of both functions...

Modulus Functions

This interactive program deals with the modulus function applied to linear, quadratic, reciprocal and sine functions. The graph of each function is shown as well as the unreflected sections of the graphs.

The first...

Parabola

Parabola

This file provides a well illustrated introduction to the properties of a parabola. It begins by illustrating the...

Polar Coordinates and Curves

This file has worksheets showing seven polar coordinate diagrams. The first allows students to explore simple polar coordinates by either inputting values for r and θ or stating those values for computer generated points. This is followed by two interactive sheets...

Proof

This interactive workbook begins with a sheet which illustrate properties of odd, even and consecutive numbers. These properties are illustrated numerically and algebraically. The next two sheets deal with properties of the sum, difference and product of these numbers...

Reciprocal Function

This interactive file shows the graphs of functions and the graph of the corresponding reciprocal function. It begins with the graph of a linear function where the gradient and intercept can be changed. The reciprocal is plotted on the same diagram. The next two sheets...

SIGMA Notation (Linear)

This file illustrates the use of the Sigma notation particularly with linear expressions. It begins with a static sheet showing four examples including some non-linear examples suitable for class discussion.

The...

Simultaneous Equations (Non-Linear)

This file provides practice at solving pairs of simultaneous equations where at least one is not linear. The pairs of graphs and the coordinates of the points of intersection can be revealed.

The first sheet deals...
