Plot the corresponding reference circle for given SHM, indicate the initial `( t=0)` position of the paritcle, the radius of the circle , and the angular speed of the rotating paritcle. Consider anticlockwise direction for rotation. `x= - 3 sin ( 2 t + (pi)/(4))` (Express in the form , `x=` Acos ( omega t + phi))`.

Plot the corresponding reference circle for given SHM x = 2 cos ((pi)/(3) -t) .Indicate the initial ( t- 0) position of the particle , the radius of the circle and the angular speed of the rotating particle . Consider anticlockwise direction for rotation. Hint : x = 2 cos ((pi)/(3) -t)=2 cos ( t- (pi)/(3)) as cos ( - theta) = cos theta . Compare with x= A cos ( omegat + phi)
