      SOH CAH TOA is just a trick to make rote memorization of procedure easier. Understanding the unit circle will let you understand what trigonometry is actually doing.

      Yeah, dividing a circle into 360 parts, then subdividing those by 60, and further subdividing those by 60 makes so much more sense than just using ratio of a number fundamental to circles themselves.
