Question

I am not sure on how to approach this problem...

For the following exercises, use this scenario: A child enters a carousel that takes one minute to revolve once around. The child enters at the point (0,1), that is, on the due north position. Assume the carousel revolves counter clockwise. Time 15 sec 45 sec 90 sec 125 sec 0.707 -0.707 At what times will the child have coordinates (0.707,-0.707) if the ride last 6 minutes?
