There are several approaches to factoring polynomials. Some are easier than others depending on the polynomial you are trying to factor. Here’s a step by step method to help you on the way to selecting the “best” approach to use. This article only considers real solutions and does not deal with complex solutions.
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 »
