Q. How do the trig fractions relate to the Unit Circle?
A. If we focus on Sine, we know that sine is positive and negative on certain sides. The Unit circle is the same by expanding to a graph line, and not a circle. The periods will be the one time point that will go through the cycle. The amplitudes is the distance between the highest and lowest points on the graph. It is like the angle of a point in a unit circle.
