Chapter 4, Problem 4.1.1.239(choose chapter or problem)
Damped Harmonic Motion A weight suspended from a spring is set into motion. Its displacement d from equilibrium is modeled by the equation
\(d=0.4 e^{-0.2 t} \cos 4 t\),
where d is the displacement in inches and t is the time in seconds. Find the displacement at the given time. Use radian mode.
(a) t = 0
(b) t = 3
