Unit Circles & 6 Trig Functions

Today we continued learning about learning circles. We had to draw our own unit circle. Drawing my own diagram helped me understand the relationship between the degree points, to the radian points.

Then we started learning about the 6 Trig Functions. Which are:

sin = y/1 csc = 1/y
cos = x/1 sec = 1/x
tan = y/x cot = x/y

It is kind of a confusing concept to grasp, but after doing an example question together, I feel like a kind of understand how the reciprical functions work.
