This video will help you make the transition between Unit N Concept 9 (using Unit Circle to find angle when given values) and Unit O Concept 2 (using calculator to find angle when given values. We will have to use all of the skills of Unit N (coterminal angles, reference angles, etc), but this time it will be a little trickier because the values will not be very nice numbers to work with...

Two things I want you to look and listen for in this video...

1. What is the new vocabulary for the "inverse tan" that they use?

2. When they solved the tangent equation, they said the answer was 45*. What is wrong with that answer and why?

This very quick overview will show you how to do ONE MORE STEP (add, subtract, multiply, or divide first) and then follow the same procedures as concept 2.

This is the "baby step" concept to actually solving trig equations in our later units.
