A particle in SHM is described by the displacement function, X(t) = B sin (omega t + alpha), omega (2pi)/T. If the initial (t = 0) position of the particle is lem and its initial velocity is pi cm//s, what are its amplitude uninitial phase angle ? The angular frequency of the particle is pi//s, nsqrt(2), mpi//4 then n & m are
