The difference in length of a spring on a pogo stick from its non-compressed length when a teenager is jumping on it after 0 seconds can be described by the function y = 2cos0 + v3 Part A: Determine, algebraically, all values where the pogo stick's spring will be equal to its non-compressed length. Show all necessary calculations. (6 points) Part B: If the angle was doubled, that is 0 became 20, what are the solutions in the interval [0, 2TT)? Solve algebraically and show all necessary calculations. How do these compare to the original function? (6 points)
