Mathematical Language

This introductory section provides useful background material on the importance of symbols in mathematical work. It describes conventions used by mathematicians, engineers, and scientists.

Powers or Indices

A knowledge of powers, or indices as they are often called, is essential for an understanding of most algebraic processes. In this section you will learn about powers and rules…

Logarithms

Logarithms appear in all sorts of calculations in engineering and science, business and economics. Before the days of calculators they were used to assist in the process of multiplication by…

Substitution and Formulae

In mathematics, engineering and science, formulae are used to relate physical quantities to each other. They provide rules so that if we know the values of certain quantities; we can…

Expanding and Removing Brackets

In this unit we see how to expand an expression containing brackets. By this we mean to rewrite the expression in an equivalent form without any brackets in. Fluency with…

Pascal's Triangle and the Binomial Theorem

A binomial expression is the sum or difference of two terms. For example, x+1 and 3x+2y are both binomial expressions. If we want to raise a binomial expression to a…

Factorising Quadratics

An essential skill in many applications is the ability to factorise quadratic expressions. In this unit you will see that this can be thought of as reversing the process used…

Transposition of Formulae

It is often useful to rearrange, or transpose, a formula in order to write it in a different, but equivalent form. This unit explains the procedure for doing this.

Linear Equations in One Variable

In this unit we give examples of simple linear equations and show you how these can be solved. In any equation there is an unknown quantity, x say, that we…

Completing the Square

In this unit we consider how quadratic expressions can be written in an equivalent form using the technique known as completing the square. This technique has applications in a number…

Completing the Square (max, min)

Completing the square is an algebraic technique which has several applications. These include the solution of quadratic equations. In this unit we use it to find the maximum or minimum…

Quadratic Equations

This unit is about the solution of quadratic equations. These take the form ax^2+bx+c = 0. We will look at four methods: solution by factorisation, solution by completing the square,…

Simultaneous Linear Equations

The purpose of this section is to look at the solution of simultaneous linear equations. We will see that solving a pair of simultaneous equations is equivalent to finding the…

Solving Inequalities

Inequalities are mathematical expressions involving the symbols >, <, >= and <= . To 'solve' an inequality means to find a range, or ranges, of values that an unknown x…

Cubic Equations

All cubic equations have either one real root, or three real roots. In this unit we explore why this is so.

Simplifying Fractions

The ability to simplify fractions and to write them in equivalent forms is an essential mathematical skill required of all engineers and physical scientists. This unit explains how these processes…

Polynomial Division

In order to simplify certain sorts of algebraic fraction we need a process known as polynomial division. This unit describes this process.

Partial Fractions

After reading this text, and/or viewing the video tutorial on this topic, you should be able to: * explain the meaning of the terms 'proper fraction' and 'improper fraction' *…

Symmetry: Revitalizing Quadratics Algebra

Learn why quadratic equations have "quad" in their name, even though they don't involve anything to the 4th power. Then try increasingly challenging examples, finding the solutions by sketching a square. Finally, derive the quadratic formula, which you've been using all along without realizing it.

Moving Bodies with Constant Mass

A compilation of the following programs: : Deceleration with parachutes, Acceleration with planes, Bows and Arrows, Differentiation of natural log of x (tutorial), Inverse Trig function - differentiation (tutorial), Exponential Functions (tutorial), Integrals that lead to log functions (tutorial), Integration by substitution (tutorial), Partial Fractions (tutorial) and Differential Equations -…

Symmetry: Revitalizing Quadratics Graphing

Throw away the quadratic formula you learned in algebra class. Instead, use the power of symmetry to graph quadratic functions with surprising ease. Try a succession of increasingly scary-looking quadratic problems. Then see something totally magical not to be found in textbooks.

Linear Equations and Their Graphs

Key concepts explained: linear equations and their graphs, and the domain of an equation.

Factoring is Fantastic

Key concepts explained: Factoring, terms, expressions, finding the greatest common factor(s), and factoring polynomial expressions that are the sums or differences of terms with common factors.
This starts with a review of numerical factors and greatest common factors, and
moves into the realm of algebra. Different types of factoring and…

Integration

The 11 videos in this collection focus on all aspects of Integration, from integration as summation to integration leading to log functions.

The Joy of Higher Algebra

This lecture shows how to solve quadratic (second-degree) equations from the technique of completing the square and the quadratic formula. The quadratic formula reveals the connection between Fibonacci numbers and the golden ratio.

Trigonometry

The 11 videos in this collection focus on all aspects of Trigonometry, from Pythagoras' theorem to cosec, sec and cot.

Arithmetic

The 8 videos in this collection focus on all aspects of Arithmetic, from fractions to percentages and ratios.

Functions and Graphs

The 8 videos in this collection focus on all aspects of Functions and Graphs.

Moving Bodies with Variable Mass

A compilation of the following programs: Impluse, Rockets and Avalanches, Integrals that lead to log functions (tutorial) and Differential Equations - variables separable (tutorial)

Algebra: A Piece of Cake

Covers variable, numerical substitution, algebraic conventions, developing algebraic formulas from number patterns.
