Laws of Indices and Logarithms

Monday, August 18th, 2008

Memorise these indices and logarithms laws. Indices and logarithms are two different ways of saying the same thing. For example:

y=\log_{a}x is read as “a raised to the power of y equals x“.

that is:

a^{y}=x.

Factors of quadratics

Wednesday, August 13th, 2008

When 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

Friday, August 8th, 2008

Multiplying matrices is fairly simple but there is a process to learn and a couple of rules to remember.
