 Apr16 revised Fair rolling for a six sided die Formatting. Apr16 suggested approved edit on Fair rolling for a six sided die Apr3 asked What multigraphs are isomorphic to their dual graph? Nov22 revised How can the trefoil knot be expressed in polar coordinates? Added title's question to body. Nov22 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? Nov22 asked How can the trefoil knot be expressed in polar coordinates? Oct31 comment Why does this function not have any extrema? Indeed, plotting the function shows that there is a saddle point.

Writing out all 9 cases is not that bad, honestly. Oct30 comment Why am I getting half the correct answer by using Green's Theorem? That, and I remember it's the Jacobian for that transformation.
