Q.1) Two dimensional isotropic oscillator with initial conditions x = A, y = 4A,i = 0, y = 3wA at t = 0 at t = 0,where o is the angular frequency. x(t) = Acos(@t + 0), y(t) = Bcos(wt + 4) (a) Find x(t) and y(t) explicitly. (b) Describe the motion 00000 00000 (c) Evaluate the angle of the semi major axis with respect to the x- axis. (d) Draw the path in the x-y plane.
