The displacement from equilibrium of an oscillating mass attached to a spring is given byy(t) =3cos5t

whereyis measured in inches andtin seconds. Find the displacement at the times indicated in the table. (Round your answers to three decimal places.)

a) t= 0.25

b) t= 0.50

c) t= 0.75

d) t= 1.00

e) t= 1.25

any help is greatly appreciated!
