Answer:

x²-2y-1 = 0 is your answer

Step-by-step explanation:

  • we have , x=cosθ+sin
  • by squaring both sides, x² =sin²θ + cos²θ+2*cosθ*sinθ.............................................................................(i)
  • and we have also, y=cosθ×sinθ
  • =by multiplying 2 in both sides , we get, 2y=2×cosθ×sinθ
  • by putting the value of 2y in equation (i) we get
  • x²=sin²θ+cos²θ+2y {sin²θ+cos²θ=1}
  • x²=1+2y
  • x²-2y-1=0(Ans.)
