Consider the parametric curve: $$x=6\cos^3(t), y=6\sin^3(t)$$ Write it in Cartesian form.
I am really struggling with the solution for this. I've been trying to find $t$ from $x$, and then plugging that into $y$, but it ends up being too complicated.
It is asked to be put in the form $F(x,y)=c$, for some function $F,$ and some constant $c$.
Any help at all would be appreciated, thank you.
