### Gradient

This excel program contains a series of interactive spread sheets designed to explore the concept of a gradient of a curve.

The first activity illustrates that the gradient of a function, at a point P, is the gradient of a chord PQ as the length of PQ tends to zero. The equation of the quadratic can be...

### Graphical Solution of Equations

This resource is an interactive excel program to enable students to investigate the solution of polynomial equations up to cubics using a graphical method.

The program shows the graphs of cubic equations and the equivalent tables of values. There is a set of questions requiring students to solve equations...

### Growth and Decay

This resource is an interactive excel program to enable students to investigate exponential growth and decay. The topics of the interactive sheets are depreciation, exponential growth of bacteria and half life and radioactive decay.

Each of the interactive sheets shows the graph of the function and there are...

### Numerical Methods

### Transformation of Functions

This interactive excel program allows students to explore the relationship between the transformation of functions and the associated graphs. Functions explored are straight lines, quadratic and cubic functions as well as sine and cosine curves. Each type of function can be fully transformed in stages. The...

### 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 to show how it affects the remainder. Some of...
