							Let any point on line be ((4-3t)/2,tThus equation of chord of contact given by: [T=0] will be [X(4-3t)/2 + Yt - 1=0] which will always pass through (1/2,3/4).

							You are looking for the pole of the line 2x+3y=4 w.r.t to the circle x2+y2 = 1. If the point is (x1, y1), then the polar of the point would be xx1+yy1 = 1. Comparing with 2x+3y = 4, we immediately get $\frac{x_1}{2} = \frac{y_1}{3} =\frac{1}{4}$ so that x1 = ½, and y1 = ¾
