Two tangents are drawn from (-2, -1) to the parabola y 2 = 4x. If ‘ α α ‘ is the angle between them, then tan α α =
Text Solution
Verified by ExpertsThe correct answer is:
A
Angle between the tangents drawn to the parabola S ≡ ≡ y 2 – 4ax from (x 1 , y 1 ) is 
given S ≡ ≡ y 2 – 4x, (x 1 ,y 1 ) =(-2, -1).
∴ ∴ tan α α =
