Finding the x and y coordinates for a given point on the unit circle

The video tutorial explains how to determine the X and Y coordinates of points using reflections over the X and Y axes. It emphasizes the importance of memorizing key points in the first quadrant of the unit circle, such as π/4 and 1/2, sqrt 3/2. The tutorial also covers how to reflect these points over the axes and the resulting changes in their coordinates.

What are the coordinates of the first quadrant point that should be memorized?

Explain how to find the coordinate point for two lines based on reflections.
