Thanks in advance.Name:  Screenshot 2019-11-08 at 11.59.15.png

...
x(t) = Acos(wt), w = 10.5 rad/s is fine (displacement in SHM is often horiz, thus x instead of y).

Note SHM eqn w/o phase shift i.e) starting at origin, is x(t) = Asin(wt). From +A is pi/2 phase shift, so x(t) = Asin(wt + pi/2) = Acos(wt).

More importantly: T = 1/f = 0.6 s (1 d.p) but your graph shows T of over 2 s. The horiz axis should be time (s).
