A weight is oscillating on the end of a spring (see figure). The displacement from equilibrium of the weight relative to the point of equilibrium is given by y = 12(cos(8t). - 4 sin(8t)) where y is the displacement (in meters) and t is the time (in seconds). Find the times when the weight is at the point of equilibrium (y=0) for 0 ≤t≤ 1. (Enter your answers as a comma-separated list. Round your answers to two decimal places.) t =
