anonymous one year ago Convert the polar equation r^2 = 2sin2Ө to a Cartesian equation. Answer choices: (x^2 + y^2)^2 = 2xy (x^2 + y^2)^2 = 4xy (x^2 + y^2)^2 = 2y^2

One trick you might want to note for this one is the following fact: $\sin(2\theta) = 2 \sin(\theta)\cos(\theta)$ That might be useful for you when you try to convert.

No worries, feel free to repost the question if you get stuck. You should have the basic information you need to succeed now though. :) Good luck!
