Finding Stationary Points and Local Extreme Values-Find the gradient of the function then set it equal to zero. Solving for x and y gives the critical points of the function.-Use the second partials test to classify the points as a local min/max or saddle point. Absolute Extreme Values -Determine the critical points – the interior points at which the gradient is zero or does not exist. -Determine the points at the boundary that could give rise to extreme values by parametrizing the boundary to some function r = r(t).
