## The Exponential Function

In this section, you will learn

- the
*Definition*and some*Characteristics*of the Exponential Function, - how
*Growth*and*Decay*can be represented mathematically and - what the
*Hyperbolic Functions*are. - In every chapter, you will also see various
*examples*helping you to apply the methods taught in that section.

Videos - To give you the possibility to apply the content learned in the videos, you should try to solve the following series of exercices:

Series 1

## Complex Numbers

- In the second chapter, you will learn some
*Definitions*and*Rules for Calculation*with Complex Numbers, - to use a
*Graphic Representation*of Complex Numbers and in that context you will learn to know the widely used term*Polar Coordinates*and see how we can apply this with Complex Numbers and - you will learn the definitions of
*Eulers Formula*and of*de Moivre's Formula* - As in the previous chapter, you will also see various examples helping you to apply the methods taught in that section
