Finding extrema

WebJan 26, 2024 · How To Find Global Extrema — Multivariable Thankfully, finding absolute extrema for functions of several variables is similar to those techniques we used in single variable calculus. Identify critical points (stationary points) for the given function by setting the first order partial derivatives equal to zero and solving.
