point form is only applicable for a point on the curve.
sir I have one problem which is too similar which you have solved in this courses,but when I am trying via this method it can't solved. Q.Angle between the tangents drawn from (5,4) to the ellipse x²/25 + y²/16 = 1 is→ (a) π/3 (b) π/2 (c)2π/3 (d)π/4 when I'm doing same method which have done, "m" is not in quadratic,even it comes Zero.
