This topic focuses on determining the coordinates of points on the unit circle at specific angles, measured in degrees. The angles used here are multiples of 45° (examples include 45°, 135°, 225°, and 315°). Students are asked to identify the correct coordinates corresponding to given angles, advancing their skills in trigonometry and the unit circle concept. Each question presents multiple-choice answers, enhancing a learner's ability to connect visual or theoretical angle measures to their exact point representations on the circle. This is a fundamental skill in trigonometry that aids in understanding sinusoidal functions and their real-life applications.
