1. The height (in inches) of a toy that moves up and down on a spring can be modeled by the function y = -(cos x)+ 2(cos a)(sin x) where x is time in seconds. Within the interval 0 < x < 6, when does the toy reach its minimum height? What is that height? a height of 1.76 inches at 3.776 seconds a height of -1.76 inches at 5.647 seconds
