Question

Which of the following equation does not represent a simple harmonic motion

• A. $y = a\sin\omega t$
• B. $y = a\cos\omega t$
• C. $y = a\sin\omega t + b\cos\omega t$
• D. $y = a\tan\omega t$

Answer 1

Answer: (D)

$y = a\tan\omega t$

Answer 2

Standard equation of S.H.M. $\frac{d^{2}y}{dt^{2}} = - \omega^{2}y,$ is not satisfied by $y = a\tan\omega t$.
