Sign in to comment. We can see by the parametrizations of x and y that when t = ± 1, x = 0 and y = 0. If the amplitude of the oscillation is a, then the time period is simply, where v is the velocity and as the question states, one-quarter of a period is time to move from 0 to a. We can't let Δx become 0 (because that would be dividing by 0), but we can make it head towards zero and call it "dx": Δx dx. Reduce Δx close to 0.
