WebThe definitions of chord of contact, pole and polar of a parabola are exactly same as that of a circle. Chord of contact: If two tangents are drawn to a conic from an external point, … WebEquation of Chord of Contact of Tangents The general equation of the circle is x 2 + y 2 + 2gx + 2fy + c = 0 Let P (x 1, y 1) be a point outside the circle. Let the tangents from P (x 1, y 1) touch the circle at Q (x 2, y 2) and R (x 3, y 3 ). The equation of the tangent PQ at Q (x 2, y 2) is xx 2 + yy 2 + g (x + x 2) + f (y + y 2) + c = 0

WebEquation of chord of contact from p (h,k) to x 2 + y 2 = a 2 is xh + yk = a 2 this line touches (x) 2 + (y-a) 2 = a 2 substituting x= (a 2 -yk)/h from the first equation, we get a quadratic in y.The line touches the second circle in only one point, so discriminant should be equal to … WebThe chord AB joining the points of contact A and B of the tangents from P is called the chord of contact of P (x 1, y 1) with respect to the circle. Its equation is given by T = 0. Example; Let P be any moving point on the circle x 2 + y 2 − 2x = 1 , from this point chord of contact is drawn w.r.t. the circle x 2 + y 2 − 2x = 0. herman hwang
