Limits theorems are used to find a limit for function that may be comprised of many terms. Using the theorems split the original function into 2 or more functions and evaluate the limits to each part seperately. Then recombine each individual limit to get the limit of the original function. (more…)
As discussed in graphs of exponential functions the most informative approach is to view the general form
as a set of transformations.
These transformations are summarised here in tabular form. (more…)
By comparing logarithmic functions with the simple form it is easy to sketch their graphs using a transformational approach. (more…)
By comparing exponential and logarithmic functions with their simplest forms it is easy to sketch their graphs using a transformational approach.
Memorise 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:
