# Introduction of trigonometry

A History of Mathematics.  Would You Rather Listen to the Lesson? Introduction to Trigonometry - Where to Start! Before you even mention you are starting trigonometry take them through a real world problem. Example Problem to Start With: Pick one student from your class.

Preferably one who doesn't usually pay attention Let's say his name is Johnny. Draw them a picture on the board like this! Johnny's dog is at the bottom of a cliff looking up at him. What is the angle of elevation between the dog and Johnny?

Is there a tool we can use to find this? If this were actually happening in the real world. Johnny was actually on a cliff looking for his dog.

## Welcome to She Loves Math!

We really needed to measure the angle of elevation. The only information we have is that the dog is ft away and Johnny is 50 ft up the cliff from the dogs eye site. How could we measure this and with what tool?

You will need to use Trigonometry to find this angle. Ask them to give you other examples. Maybe give them a few more.
