This was an interesting activity/test because it was different from anything you ever do in a math class or just a class in general. It actually helped me make a lot of connections because I was doing the problems hands on which is how I learn best. I learned how the unit circle helps a lot with where the points for each function is located on a graph. Before the activity I did not understand how the unit circle even related to what we were doing but when working on this activity I learned that each spot like pi/6 can be calculated either using sin or cos and you can find what the y value would be at pi/6. I also learned how sin is the rise and cos is the run and I can actually picture it in my head of what that look like. Like sin(0) would be one because you go out 1 unit to get to the 0. So on the graph you would go to (0,0) and that is the point. When finding the angle on the unit circle you can find the point on the coordinate plane. It was very weird not to find out the answer to the problem and the Mr. Cresswell to just stand there and have no reaction but saying is that your final answer. It made me kind of second guess myself if I had done it right or if I was completely wrong. At the end when he asked if we wanted to make any corrections that was the worst part because I went through them all in my head to remember if we did them all right. In the long run though it was very helpful to see physically how the unit circle and coordinate plane go together. It was also helpful to see that we really could do it on our own and we succeeded.
