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. Read the rest of this entry »
If you have an equation and want to solve for an unknown in the exponent simply take the logarithm of both sides and apply the indices/logarithms laws.
An example follows: Read the rest of this entry »
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. Read the rest of this entry »
By comparing logarithmic functions with the simple form it is easy to sketch their graphs using a transformational approach. Read the rest of this entry »
