Possible answers: The numbers tend to repeat themselves. There is a pattern to the numbers as the angle increases. The highest values are 1. The lowest values are -1. It tends to cross the x-axis often. When is sin x=1? 0? Sin x = 1 when the angle in -270( and 90(. Sin x = 0 when the angle in -360(, -180(, 0(, 180( and 360(.
