Phasor Diagram

The radius of the circle, the period of revolution, initial position and direction of revolution are indicated in the figure.

The $y$ -projection of the radius vector of rotating particle $P$ will be:

1.	$y(t)%3D3%20%5Ccos%20%5Cleft(%5Cdfrac%7B%5Cpi%20%5Cmathrm%7Bt%7D%7D%7B2%7D%5Cright)$ , where $y$ in m
2.	$y(t)%3D-3%20%5Ccos%202%20%5Cpi%20t$ , where $y$ in m
3.	$y(t)%3D4%20%5Csin%20%5Cleft(%5Cdfrac%7B%5Cpi%20t%7D%7B2%7D%5Cright)$ , where $y$ in m
4.	$y(t)%3D3%20%5Ccos%20%5Cleft(%5Cdfrac%7B3%20%5Cpi%20%5Cmathrm%7Bt%7D%7D%7B2%7D%5Cright)$ , where $y$ in m
