### Numerical Methods

This resource contains two excel programs with interactive spreadsheets dealing with linear inequalities in one or two variables.

**Trial and Improvement**

This excel workbook starts with finding square roots then cube roots by trial and improvement. Similar methods are used to...

### Equations of Parallel and Perpendicular Lines

This excel program is about finding the equation of straight lines in the form ax+by+c=0. The first two sheets deals with the equation of the line through two given points and the equation of the line through a point perpendicular to a given line. The resource is an interactive excel program which allows the graphs...

**Quadratics: Rearranging and Graphing**

The first sheet shows a set of quadratic functions and the...

### Simultaneous Equations

This contains two excel programs with interactive spreadsheets designed to show the graphical solution to pairs of simultaneous equations and provide their solutions.

**Simultaneous Equations: Linear**

This excel workbook generates sets of pairs of linear equations, shows their...

### Straight Lines: Y = mX + c

This interactive excel program is about finding the equation of straight lines in the form ax+by+c=0. The first two sheets deals with the equation of the line through two given points and the equation of the line through a point perpendicular to a given line. The program allows the graphs of the lines to be shown...

### 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...

### 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 interactive sheet shows the equation and graph of circles centred on the origin where the radius...

### Functions

**Composite Functions**

The first five sheets all have a similar format. A number is operated on by two functions, one after the other. The output after each operation can be revealed. Beneath the numerical example the algebraic form for gf(x) is shown and simplified by...

### Exponential and Logarithmic Functions

**e**

This file has five sheets. The first shows how the value for e is derived from the binomial series for (1+x)^{n} and this is used on the second sheet to derive the series for ex. The third sheet finds the derivative of e^{x...}
