The following graph shows the angular position of the Lion as the disk plate rotates. It is a simple sine graph with maximum angular position of 180 degrees. As shown in the graph, after reaching its maximum angular position of 180 degrees, it returns back to its original position. Similar to the linear motion, the first half of the graph corresponds to the first disk and the second disk returns the Lion to its original place which is shown in the second half of the graph.
