find a model for simple harmonic motiond, in centimeters, with respect timet, in seconds, with an intial displacement (t=0) of 0 centimeters, an amplitude of 6 centimeters, and a period of 5 seconds

period

2pi/ omega = 5

omega = 2pi/5

since the intial dissplacement is 0 we will use sin(omega)t

d = 6sin(2pi/5)t

this is where i am stuck, do i solve for d or t? or is the model is the equation?
