UPLIFTING Trigonometry Song about the Unit Circle & Exact Values for Sin, Cos, Tan

This video and song explain how to find exact values for sine, cosine and tangent for 30, 45, 60 with two "special triangles". Also how to use the symmetry of the unit circle to find exact values for other angles such as 90, 120, 135, 150, 180 etc.
In radians, any multiple of π/6 or π/4 can be found using the two triangles and unit circle symmetry.
These videos explain the topic in more detail (without music):
What is a radian?
UNDERSTAND the exact values and the unit circle
The original uplifting and beautiful song "Wake Me Up" was written by Avicii, Aloe Blacc and Mike Einziger.
I mixed this version of the song using the amazing free music creation tool at beepbox.co
