Homework Statement
I have this equation and i need to find the cartesian equation, so i apreciate your help
Homework Equations
X=cost ' y=2sin2t
The Attempt at a Solution
I am usign this [/B]
Sin2t=2costsint
So x+y/2=cost+2costsint
But i don't know what to do after,
I also try to solve that this way
Y/2=sin2t
Y/2=2costsint then sint=y/(4cost)
Y/2=2((x)y/4x)
When i isolate y i get y/y=3x-2
