Task id13571

Write the equations of phase trajectories for oscillations S1, S2, S3 (see task. (Plot graphs of the following harmonic oscillations: S1(t) = 2cosw1t, S2(t) = cos(wt + ), S3 = 3cos(wt + ), w1 = 200p rad/s, w = 100p rad/s. Draw the oscillatory processes S1(t), S2(t) and S3(t) as vectors. Find the complex amplitude of these oscillations. Find the amplitude and initial phase of the oscillation, which is the sum of oscillations S2 and S3.)). Find the position of the representing point on the phase plane for these oscillations in m
