Out of the following functions representing motion of a particle which represents SHM
I. `y = sin omega t - cos omega t`
II. `y = sin^(3)omega t`
III. `y = 5 cos ((3 pi)/(4)-3 omega t)`
IV. `y = 1 + omega t + omega^(2)t^(2)`

A

Only (1) and (2)

B

Only (1)

C

Only (4) does not represent SHM

D

Only (1) and (3)

Text Solution

Verified by Experts

The correct Answer is:
D
