Q. Which of the following function represents a simple harmonic oscillation
A) $\sin{\omega t - \cos{\omega t}}$
B) $\sin^{2}{\omega t}$
C) $\sin{\omega t + \sin{2\omega t}}$
D) $\sin{\omega t - \sin{2\omega t}}$
Explanation
(a) The standard differential equation in satisfied by only the function $\sin{\omega t - \cos{\omega t.}}$ Hence it represents S.H.M.
