| | THE **SINE** FUNCTION Ronald G. Sienkiewicz Prosser Vocational High School Chicago, IL 60639 1-312-637-5556 Objectives: To familiarize the students with the concept of the **sine** function by defining, by graphing, by computer generating, by using a "shop created" flboard **sine** wave generator, and by presenting examples of natural phenomena which result in **sine** wave motion. |

| | Writing an equation on the chalkboard and asking the students to predict its graph, I was able to quickly and efficiently run through several variations of the **sine** function without the tediousness of using the chalkboard. |

| | The significant idea here, being that this type of motion (the movement of a pendulum and the motion of a mass at the end of a spring-natural phenomena) will always be mathematically expressed in terms of **sines** and cosines. |
