Took Robert's work with cylindrical coordinates and shamelessly adapted it for class in the morning. Robert's example verbatim, then a second example with a function from the textbook having a min and a saddle point. Placed a circle in the domain in between these two locations (dropped it down 4 units in the plot, since the vertical was getting a bit busy). Managed to capture a portion of the surface shaped like a Pringle's chip. I'll talk about extremes along the boundary as we cover Lagrange multipliers tomorrow.
