comment How can the trefoil knot be expressed in polar coordinates?
But the Wolfram|Alpha plots both treat $t$ analogously to $\theta$. In the first, $0 < t < 2\pi$ and in the second $-\pi < t < \pi$. How is $t$ different from $\theta$ in these contexts?

comment Why does this function not have any extrema?
Indeed, plotting the function shows that there is a saddle point.

comment Finding the limit of $( 1 + a + a^2 + \ldots+ a^n)/(1 + b + b^2 + \ldots+ b^n)$
The method I tried turned out to give a wrong answer, so I deleted my answer. Writing out all 9 cases is not that bad, honestly.

That, and I remember it's the Jacobian for that transformation.

D'oh! That's exactly it! In my defense, the last time I had to worry about that was more than two years ago... >_>
