I instructed Olivia to make a chart of the following columns: across the top were radian angles, coordinates, quadrants, and degrees. Down the side were all of the special angles on the unit circle. I explained each of the entries in the chart as we filled it in together. After we finished the chart, I demonstrated how the information could be used with the definitions of each trigonometric function to find the values. We did a couple of problems. There was no assignment.
