Finding coordinates on a unit circle

WebA point with coordinates ( a, b) is in the unit circle if and only if a 2 + b 2 = 1. Explanation: The unit circle is by definition a circle with radius equal to 1 and center ( 0, 0), so the distance of the points ( x, y) in that circle to the center is equal to 1, hence by the distance formula : a 2 + b 2 = 1 a 2 + b 2 = 1. Share Cite Follow WebFeb 27, 2024 · So far I have only used polygons, but I want to move to circles. The problem I have run into is extracting the individual coordinate points of a circle and even storing that data in a matrix. I think I might have to loop over the values for the angle theta to store values as x and y coordinates, but I'm not sure how to do that.
