Q3 The displacement from equilibrium of an oscillating mass attached to a spring is given by y(1) = 4 cos( 2xx) , where y is measured in inches and t in seconds. By using an appropriate standard engineering software such as MATLAB, CAS calculator, programmable calculator, Excel software, compute the displacement at the times indicated in the table. y(1 ) O 0.25 y>0 0.50 --- -. Equilibrium, y = 0 0.75 1.00 y
