For particle P revolving round the centre O with radius of circular path r and angular velocity `omega`, as shown in below figure, the projection of OP on the x-axis at time t is

`x(t)=rcos (`omega`t +`pi`/6)

`x(t)=rsin(`omega`t+pi/6)`

`x(t)`=`rcos (`omega`t - pi/6`omega`)

`x(t)` = rcos(`omega`t)
