Plot the corresponding reference circle for each of the followingsimple harmonic motions. Indicate the initial (t = 0) positionof the particle, the radius of the circle, and the angular speed ofthe rotating particle. For simplicity, the sense of rotation may befixed to be anticlockwise in every case: (x is in cm and tis in s).(a) x = –2 sin (3t + π/3)(b) x = cos (π/6 – t)(c) x = 3 sin (2πt + π/4)(d) x = 2 cos πt |
