Module 6 Introduction

 

Many patterns in nature regularly repeat themselves. Consider temperatures throughout the year. In summer, temperatures are high. Temperatures slowly drop to become low in winter; then the temperatures gradually increase to become warmest again in summer. In this module you will explore some periodic functions—these are functions that allow you to mathematically represent a pattern like daily temperatures.
