RE: Find minimum or maximum of multi-variable function
Another plot you could consider is one showing where there two partial derivatives are non-negative and then look for overlapping boundaries. Two things to watch out for with this approach is where the partial derivatives are discontinuous or are locally constant (zero in particular). With this example, the regions are larger and the three colours more obvious in an Advanced Graphing plot, as shown by the attached screenshot.
