Which of the following functions of time represent (a) simple harmonic (b) periodic but not simple harmonic and (c ) non periodic motion? Give period for each case of periodic motion `(omega` is nay positive constant) (1) `Sin^(3) omegat` (2) `3cos (pi//4 -2 omegat)` (3) `cos omegat +cos 3 omegat + cos 5 omegat` (4) `e^(-omega^(2)t^(2))` (5) `1 + omegat +omega^(2) t^(2)`
