Define phase at time t and initial phase.

The motion of a particle executing simple harmonic motion is described by the displacement function, x(t)=Acos(omegat+phi) . If the initial (t = 0) position of the particle is 1 cm and its initial velocity is omega cm/s, what are its amplitude and initial phase angle ? The angular frequency of the particle is pi s^(-1) . If instead of the cosine function, we choose the sine function to describe the SHM : x = B sin (omegat + alpha) , what are the amplitude and initial phase of the particle with the above initial conditions.

A particle is executing SHM given by x = A sin (pit + phi) . The initial displacement of particle is 1 cm and its initial velocity is pi cm//sec . Find the amplitude of motion and initial phase of the particle.

The displacement of a simple harmonic oscillator is given by y= 0.40 sin (440t +0.61) . For this, what are the value of initial phase?

Explain by drawing graphs of displacement x(t) to t , velocity v(t) to t and acceleration a(t) to t of SHM for initial phase zero.
