Ok so as I was typing out my work, I realized a mistake I made. So now I'm down to:
(cosθ)^2+(sinθ)^2+2cosθsinθ=1
Am I going to need to use some kind of trig substitution to solve this now?
I was given the problem r=2sin(2(θ)). I'm supposed to write the equation in the Cartesian Coordinates. I understand the basics to this but I'm not really sure how I'm supposed to write the equation when I have x=2sin(2(θ))cos(θ) and y=2sin(2θ)sin(θ).
