Question

Explain how the special angles are used to find the coordinate points around the Unit Circle and how you find the sine, cosine, and tangent values of the special angles using the Unit Circle.

Answer 1

if you take a look at the unit circle, the angles are multiples of 30/60/45, etc. that correspond to the 30-60-90 triangle and the 45-45-90 triangles, which have specific side ratios that makes it easier to calculate the side lengths, and thus the cos/sin values each coordinate on the unit circle is given as a function of (costheta, sintheta) so you would use the x and y-coordinates to find cos and sin then calculate tan based on that

Answer 2

Thank you so so so so much, again!!!
