1.	Which of the following expression does not repressent SHM?A. `A cos omega t`B. `A sin2 omega t`C. `A sin omega t + B cos omega t `D. `A sin^(2) omega t`
Answer» Correct Answer - D For `SHM (d^(2)y)/(dt^(2)) prop - y` If `y = A sin^(2) omega t` `(dy)/(dt) = (2A sin omega t cos omega t ) omega` ltbnrgt `= A omega sin 2 omega t` `(d^(2)y)/(dt^(2)) = + 2 A omega^(2) cos 2 omega t` `i.e. (d^(2)y)/(dt^(2))` is not proportional to `- y`
