Return to Topic List

The Algebra section of the Standard Level course is relatively short, in fact there are only three chapters within the topic.

1.1 Arithmetic sequences and series; sum of finite arithmetic series; geometric sequences and series; sum of finite and infinite geometric series. Sigma notation.

Here is my attempt to explain what is meant by a sequence and a series, both arithmetic and geometric. The first topic of the course seems to throw up a lot of formulae which can seem a bit daunting at first but try to stick with it. They are in your formula booklet but as with all the formulae you will cover throughout the course you need to be familiar with the notation (how the formula is written) and to understand how and when to use the formula. This means your formula booklet is not a replacement for understanding. An Introduction to Sequences and Series

1.2 Exponents and logarithms. Laws of exponents; laws of logarithms. Change of base.

Exponents may be familiar but what is a logarithm? Can you remember all those fiddly laws of logs? If so then here you can download this puzzle which will test your ability to match the equivalent expressions

1.3 The binomial theorem: expansion of (a + b) n, n e N  **In addition on the 2014 syllabus** **Calculation of binomial coefficients using Pascal's triangle and (n r)**
