WebSince the tangent line has to pass through the circle as well as ellipse it should intersect both of them at coinciding points (equal roots). Thus if you look at circle line intersection then you can get. x 2 + ( k x + n) 2 = 4. This is a quadratic in x and it should have two equal roots (for tangency). Thus the discriminant should be 0. WebApr 7, 2024 · Hint: We will first try to plot the graph of the two curves and then prove that if there is no point of contact then there will be no common tangent between the two given curves.
