I learned and memorized a lot more about the unit circle than I had before. I've memorized that every spot on the unit circle increases by π /12 units. This activity also helped me to remember the side lengths/angles of the 30-60-90 and 45-45-90 triangles. Also, this helped explain why sine/cosine = tangent, and why sine is equal to rise, cosine is equal to run, and tangent is equal to the slope. This activity also helped visually connect the unit circle and the coordinate plane. You could see a point on the unit circle and relate it to how you got the answer that's on the plane. I was confident in my answers when you couldn't help us , but some of the questions you asked made me think twice. Thanks for reading.
