From the point P(1, 
) on the circle x 2 + y 2 = 4 a tangent is drawn to the hyperbola 
which meets its transverse axis at Q. From Q a line is drawn parallel to conjugate axis, which cuts the hyperbola at R above the x-axis, then PR equals
A
3
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
A
P = (1, 
) = 
Recall the definition of parametric point on hyperbola, we have
R = 
∴ ∴ PR = 4 - 1 = 3.
