Answer:
   y = (x/(1-x))√(1-x²)
Step-by-step explanation:
The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:
   x = r·cos(θ)
   y = r·sin(θ)
   x² +y² = r²
__
   r = sec(θ) -2cos(θ)
   r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)
   r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²
   (x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations
   x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor
   y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)

The attached graph shows the equivalence of the polar and rectangular forms.
