2 The standard circle is drawn with the 0 degree starting point at the intersection of the circle and the x-axis with a positive angle going in the counter-clockwise direction Thus, the standard textbook parameterization is: x=cos t y=sin t In your drawing you have a different scenario
- trigonometry - Tips for understanding the unit circle - Mathematics . . .
By "unit circle", I mean a certain conceptual framework for many important trig facts and properties, NOT a big circle drawn on a sheet of paper that has angles labeled with degree measures 30, 45, 60, 90, 120, 150, etc (and or with the corresponding radian measures), along with the exact values for the sine and cosine of these angles

- Prove that the unit circle is path-connected?
For proving that the unit circle is connected, you could also say that "the only subsets of the unit circle which are both open and closed are the full circle and the empty set"

How do you characterize the set of possible values for $z$ on the unit circle, for any $k$, $l$, and $n$? I believe the values form a dense but countably infinite set
