In this activity I learned about about how sin and cosin relate to the special triangles and I learned the importance of reference angles. In this activity the main thing I learned was the point of the unit circle. Since I have missed so many days of school the unit circle was not something I spent a lot of time focusing on but now I understand that the unit circle represents the x axis in the graph. I feel like I connected a lot of dots in during this activity. I think I connected the dots between radians and degrees without using the formula to convert them back and forth due to the usage of the unit circle in making the angel. I also think I connected the dots between the x and y axis and sin and cosin. The activity helped me understand the unit circle because before I didn't really pay much attention to it because it didn't seem very relevant to me. Finding the reference angle by using the unit circle helped me understand how the unit circle relates to the graph. I did not like that Mr. Cresswell did not affirm anything because I was scared we were doing it completely wrong.
