Chord of contact formula
WebIf a line y = mx + c intersects the circle x2 + y2 = a2 in two distinct points A and B then length of intercept AB = 2√ ( (a2 (1+m2 )-c2)/ (1+m2 )) Caution: The equation of a chord of contact and the equation of the tangent on a … WebA line joining the two points of contacts of two tangents drawn from a point outside the circle, is called chord of contact of that point. If two tangents \(PT_1\) and \(PT_2\) are drawn from the point P\((x_1, y_1)\) to the circle S = \(x^2 + y^2 + 2gx + 2fy + c\) = …

The chord of … 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
WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4.
