Let BC be the chord of contact of the tangents from a point A to the circle x 2 + y 2 = 1.P is any point on the arc BC. Let PX, PY, PZ be the lengths of perpendiculars from P on the AB, BC and CA respectively then PX, PY, PZ are in
Text Solution
Verified by ExpertsThe correct answer is:
B
Let A be (0, α ) ⇒ equation of BC is α y = 1
⇒ B and C are 
and 
⇒ Equation of AC and BC are
x + 
= 1 and 
x + 
= 1
and PZ = 
where P ≡ (sin θ , cos θ )
⇒ PY 2 = PX. PZ
