Let RS be the diameter of the circle x 2 + y 2 = 1, where S is the point (1, 0). Let P be a variable point (other than R and S) on the circle and tangents to the circle at S and P meet at the point Q. The normal to the circle at P intersects a line drawn through Q parallel to RS at point E. Then the locus of E passes through the point(s)

CHECK THE SOLUTION.
(a,c)
⇒ 
Let h = 
and k = 
∴ h = 
∴ tan 
= 
⇒ 
∴ 2xy = y(1 – y 2 )
