This activity helped me see how sin, cos, and tan all affect the y values on the Cartesian plane. I think my biggest takeaway was learning that sin is rise, cos is run, and tan is rise over run. Up until this point, I didn't really understand the difference between something like sin(pi) and cos(pi). They're both the same angle on a circle graph, so they were essentially the same thing to me. Along with the special graphs, this activities allowed me to make the connection between the circle graph and the Cartesian plane. During the assessment without Mr. Cresswell, I was honestly winging it. The two special graphs were what enabled me to pass. Not knowing if i was right or wrong until the end was stressful to say the least.
