Convert the cartesian equation 2xy = 1 to a polar equation. (r^2)cosθsinθ = 1 (r^2)sin2θ = 1 (r^22)cos2θ = 1

the second option, θ=1

Step-by-step explanation:

x=rcosθ   y=rsinθ   sin2θ=2cosθsinθ

2rcosθrsinθ=1  

divide by r^2 because there are 2 r's

2cosθsinθ=1/r^2

sin2θ=1/r^2 <----multiply each side by r^2

r^2sin2θ=1

the answer is c)8

step-by-step explanaction:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
