Question

The equation of the locus of the point of intersection of the straight lines x sin θ + (1 – cos θ) y = a sin θ  and x sin θ – (1 + cos θ) y + a sin θ = 0 is 

• (A) y ± ax
• (B) x = ± ay
• (C) y² = 4x
• (D) x² + y² = a²

Answer 1

The Correct Option is D

Explanation:
$$\begin{array}{l}y=a\sin \theta \\ x=a\cos \theta \\ [x^2+y^2=a^2]\end{array}$$
