On the unit circle name all indicated angles by their first positive name, both in degrees and radians.
Unit Circle has the equationhttp://www.libraryofmath.com/pages/measure-of-angles/Images/measure-of-angles
We are going to define the 6 trigonometric functions in terms of the unit circle, a point on the circle, P(x, y), and a distance, t, that we move around the circle starting at the point (1, 0)
For t equal to any real number and P(x, y) the terminal point determined by t on the unit circle, the six trigonometric functions are as follows:
sine cosine tangent
sin t = y cos t = x tan t = y/x
csc t = 1/y sec t = 1/x cot t = x/y
