Special Functions

In this lesson I will teach you about special functions.  As the name applies there are “special” kind of functions that are not as common as the other functions we have studied.  However special functions are important and you will see there application increase as you learn more advance mathematics.  One of the most important concepts to learn in the lesson is the idea of a “piece wise” function.  These are functions that only apply to certain input values and there graphs are “pieces” on the x/y plane.  Other functions we will look at are the absolute value function, step function and recursive function.  You really need to practice the skills presented in the lesson so take good notes and spend the time you need to master the concepts.
