Part 1:. Why the second derivative test works for extrema of functions of two variables We follow the Caleulus 1 example of making sure that the first derivative is 0. And you have seen us simply set the first two partials equal to 0: f-0 and y -0. Then we apply information about a version of the second derivative, namelyDy()in concert with the sign of Ju. Why does this work? Step 1 for this part of the explanation First, is...
