Notes: 11/30




















Sorry it took me this long to post the notes. I had a few problems. Anyway, today in class we learned how to solve trig equations by using 3 main steps:
1.Get the 1st answer from the inverse trig function
2.Then the second answer from the reflection of the trig ID (Ex: Tan= 180 or 2pie+the angle)
3.Add or subtract 2 pie or 360 (depending on whether you are in degrees or radians) to both of your answers from 1 and 2 to get as many answers as needed.
