Unformatted text preview: = 1 2 is = 3 . Since the graph of cos is periodic and completes a full cycle on [0 , 2 ] and is symmetric about the line = on [0 , 2 ], we know there must be another value of at which cos = 1 2 . 0 /3 /2 3/2 5/2 2 In fact, this value of would be the same distance from 2 as 3 is from 0 (by the symmetry of the graph) . Since 3 is 3 units to the right of 0, our second point would be 3 units to the left of 2 . 2  3 = 6 3 3 = 5 3 . So our second point at which cos = 1 2 is 5 3 . 1...
