| [a] \[x=A\text{ }sin\left( \omega t+\delta \right)\] |
| [b] \[x=B\text{ }cos\text{ }(\omega t+\phi )\] |
| [c] \[x=A\text{ }tan\text{ }\left( \omega t+\phi \right)\] |
| [d] \[x=A\text{ }sin\text{ }\omega t\text{ }cos\text{ }\omega t\] |
A) a, b, c
B) b, c, d
C) a, b, d
D) a, d
Correct Answer: C
Solution :
In all above eq. only eq. \[X\,\,=\,\,A\text{ }tan\text{ }(\omega t\,\,+\,\,\phi )\] not represent of eq of SHM. \[X\,\,=\,\,A\text{ }sin\omega t\text{ }cos\omega t\] \[X=\frac{1}{2}A\,sin\,(2\omega t)\] it is eq of SHM.
