calculus - Trigonometric functions and the unit circle - Mathematics . . . Since the circumference of the unit circle happens to be $ (2\pi)$, and since (in Analytical Geometry or Trigonometry) this translates to $ (360^\circ)$, students new to Calculus are taught about radians, which is a very confusing and ambiguous term
Tips for understanding the unit circle - Mathematics Stack Exchange By "unit circle", I mean a certain conceptual framework for many important trig facts and properties, NOT a big circle drawn on a sheet of paper that has angles labeled with degree measures 30, 45, 60, 90, 120, 150, etc (and or with the corresponding radian measures), along with the exact values for the sine and cosine of these angles
How to find terminal point coordinates on a unit circle? Hey everyone I am working on a homework assignment which covers unit circles However I am really confused and having a lot of trouble locating terminal point coordinates Everything I have read on
Understanding the Unit Circle - Mathematics Stack Exchange See the StackExchange thread Tips for understanding the unit circle, and note the distinction I make in my answer between what students often see as the unit circle and what teachers see as the unit circle
