How can I find the phase angle(lead/lag) of a lead/lag network form its Lisojous pattern?

1. Ask Dick Cheney or Rumsfeld.
2. A Lissajous pattern is a graph of one frequency plotted on the y axis combined with a second frequency plotted on the x axis. Y and X are both periodic functions of time t given by equations such as x = sin (w*n*t + c) and y = sin w*t. Different patterns may be generated for different values of n(period shift) and c (phase shift). The simplest patterns are formed when n is a ratio of small whole numbers such as 1/2, 2/3, or 1/3. The value of c is usually taken as 0 or 1.57 (which is actually p /2). You obtain a perfect circle or a distorted circle depending on the phase angle.
