# Interactive video lesson plan for: Trigonometry - Find the value when the angle is larger than 90 or smaller than 0

#### Activity overview:

Sometimes we have to find the value of sin(200) where the angle is larger than 90 degrees. Other times we want to know the value of an angle less than 0 degrees. No matter what angle you have you can find a reference angle for it and quicky find the value of the function. Watch this video for how that process works.
