Coterminal Angles: Part 4. Video

Good content and explanation but much of the video cannot be seen because the screen turns black often.

Coterminal angles are not introduced until Junior and/or Senior year in a Trigonometry or Precalculus class. There is no standard that specifically address coterminal angles and are usually covered in Precalculus which is not aligned to the common core.NOTE: There is a problem with the video in that there is a black screen most of the video.
