Laws of Indices and Logarithms
August 18th, 2008Memorise these indices and logarithms laws. Indices and logarithms are two different ways of saying the same thing. For example:
is read as “
raised to the power of 
equals 
“.
that is:

Factors of quadratics
August 13th, 2008When factorising quadratics (or any trinomial) first identify the form of the expression and then apply the most direct method. If the expression is not in a recognisable form then manipulate it so that it is.
Multiplying matrices
August 8th, 2008Multiplying matrices is fairly simple but there is a process to learn and a couple of rules to remember.
Adding and subtracting matrices
August 8th, 2008Matrix addition and subtraction is fairly simple. Just remember that we can only add or subtract matrices if they have the same dimensions. The number of rows must be equal in each matrix and the number of columns must be equal in each matrix.
What are matrices?
August 8th, 2008Matrices are simply arrays of values. We use them as a tool to ease operations such as solving simultaneous equations, working with vectors and transformations.
