1. Functions

Funktionen

IEM: Functions

The chapter Functions includes:
  • Linear and Quadratic Functions
  • Power Functions, Polynomials and Power Series
  • The Exponential Function and Growth
  • Trigonometric Functions
  • Multivariable Functions
  • Curves and Maps
  • Exercises
This chapter revises some of the functions learnt about in school, namely linear and quadratic functions, power functions, the exponential function and trigonometric functions. Their basic characteristics are highlighted but most importantly they are illustrated by means of interactive diagrams. A foretaste of analysis is then given by examining both multivariable functions and a number of mapping-equations of specific curves.
