This is a multiple choice answer as classified in NCERT Exemplar

(b) y = sin3wt

= [3sinwt-4sin3wt]/4

dy/dt= [ d d t 3 s i n w t - d d t ( 4 s i n 3 w t ) ]/4

4dy/dt=3wcoswt-4 [3wcoswt]

4 * d 2 y d t 2 = - 3 w 2 s i n w t + 12 w s i n 3 w t

d 2 y d t 2 = - 3 w 2 s i n w t + 12 w 2 s i n 3 w t 4

d 2 y d t 2  is not proportional to y. hence it is not SHM.
