Question

8. Out of the following functions representing motion
of a particle which represents SHM.
(A) y = sin ot - cos at
(B) y = sin ot
(C) y=5cos 31 - 300
(D) y = 1 + ot + m2t2 [AIPMT (Prelims)-2011]
(1) Only (A) and (B)
(2) Only (A)
(3) Only (D) does not represent SHM
(4) Only (A) and (C)​

Answer 1

option 4 only A and C

Explanation:

both are in the form of general equations of SHM
