Let OP = r and angle XOP = theta then the position of P in polar coordinate system is represented by (r,theta) OX and O are called the initial line and pole respectively. If p be the length of perpendicular from origin to line and if alpha is the angle which the perpendicular to the line makes with the initial line . The equation of line is given by r cos (theta - alpha) = p Perpendicular distance from pole to the line l/r = 4 cos theta +2 sin theta is
