Show that the equation x=Asinomegat represents a simple harmonic motion.

Establish the mathematical expression for simple harmonic motion.

Displacement of a particle, in periodic motion, is represented by y = 4 cos^(2) ((t)/(2)) sin (1000t). If the equation is the superposition of n number of simple harmonic motion then n becomes
