Finding Trigonometric Coordinates on the Unit Circle Using Transformations

This lesson covers how to determine trigonometric coordinates on the unit circle using transformations. It explains the unit circle's structure, how to find coordinates for angles in different quadrants by reflecting across axes, and addresses common misconceptions about coordinate reflection. The lesson emphasizes understanding sign changes in different quadrants and concludes with a summary of the transformation process.
