WebEquation of the tangent at ‘ t ’ is ty = x + at 2. The point of intersection of the tangents at ‘t 1 ’ and ‘t 2 ’ is (at 1 t 2, a (t 1 + t 2 )). Illustration : On the parabola y 2 = 4ax, three points E, F, G are taken so that their ordinates are in G.P. Prove that the tangents at E and G intersect on the ordinate of F. WebThe equation of a tangent to the parabola y 2 = 4ax at the point of contact (x1,y1) ( x 1, y 1) is yy1 = 2a(x +x1) y y 1 = 2 a ( x + x 1). Normal: The line drawn perpendicular to tangent …
