I'm given following parametric form
$x = \cos(\sin(s))$ and $y = \sin(\sin(s))$ for $s \in \mathbb{R} \setminus 0$
I now need to determine the cartesian equation and draw the curve. I reasoned that $x^2 + y^2$ would be $\cos^2(\sin(s)) + \sin^2(\sin(s))$ and according to trigonometry that would be $1$.
So that would give me the formula for a circle with a radius $1$. But when I enter it into Wolfram, I'm given another curve: here
Any help would be appreciated!
