The displacement from equilibrium of a mass oscillating on the end of a spring suspended from a ceiling is given below, where y is the displacement (in feet) and t is the time in seconds. use a graphing utility to graph the displacement function on the interval [0, 10]. find the value of t past which the displacement is less than 3 inches from equilibrium. (round your answer to two decimal places.) y = 1.79e−0.22t cos(4.9t)
