The difference in length of a spring on a pogo stick from its non-compressed length when a teenager is jumping on it after 8 seconds can be described by the function f(0) = 2 sin0 +3. Part A: Determine all values where the pogo stick's spring will be equal to its non-compressed length. (5 points) Part B: If the angle was doubled, that is became 20, what are the solutions in the interval [0, 2n)? How do these compare to the original function? (5 points) Part C: A toddler is jumping on another pogo stick whose length of their spring can be represented by the function g(0)=1-cos0+3. At what times are the springs from the original pogo stick and the toddler's pogo stick lengths equal? (5 points)
