From an external point P, pair of tangent lines are drawn to the parabola, y2 = 4x. If θ1 and θ2 are the inclinations of these tangents with the axis of x such that, \(\theta_{1}+\theta_{2}=\frac{\pi}{4},\) then the locus of P is :
- x – y + 1 = 0
- x + y – 1 = 0
- x – y – 1 = 0
- x + y + 1 = 0
Answer
(C) x – y – 1 = 0
