Answer» Answer: Method 1 : First find point of intersection of tangents by section FORMULA. USE (T)^2=(S)*(S1) to get the equation of pair of tangents and then solve it to get two EQUATIONS separately. ... Method 2 : Assume the point of intersection of COMMON tangents to be P(h, k). And then form equation of tangent as (y-k) =m(x-h). PLEASE MAKE ME AS BRAINLIST |
