Question 851159: The displacement from the equilibrium of an oscillating mass attached to a spring is given by y(t)=4 cos 3pi(t) where y is measured in inches and t in seconds. Find the displacement at the times indicated.
t |y(t)| |y>0
0.00 | | |Equilibrium, y=0
0.25 | | |y<0
0.50 | |
0.75 | |
1.00 | |
1.25 | |
I hope this helps. I gave all information without trying display the graphic in the book. Anyways questions please email me. I'll do my best to get you more if needed. The equation is called Harmonic Motion if that helps too.

----------------------------
It's y(t) = 4cos(3pi*t)
sub the values of t and find y
t = 0, y = 4
t = 0.25, y = -2.828
t = 0.50, y = 0
etc
----------------
3pi*t is in radians I think, tho that should be specified
