The motion of a particle in S.H.M. is described by the displacement function, `x=Acos(omegat+phi)`, If the initial `(t=0)` position of the particle is 1cm and its initial velocity  is `omega cm s^(-1)`, what are  its amplitude and initial phase angle ? The angular frequency of the particle is `pis^(-1)`. If instead of the cosine function, we choos the sine function to describe the SHM`: x=B sin(omegat+alpha)`, what are the amlitude and intial phase of the particle with the above intial conditions ?
