The Answer of The function $y = 1.6 \sin ( t - 1.8 )$ models the displacement of an object moving in simple harmonic motion, where y is measured in inches and t in seconds. Find the frequency of motion.

The Function y=1.6sin⁡(t−1.8)y = 1.6 \sin ( t - 1.8 )y=1.6sin(t−1.8)

The Function $y = 1.6 \sin ( t - 1.8 )$
