The second-derivative test for maxima, minima, and saddle points has two steps. 1. Find the critical points by solving the simultaneous equations f x (x, y) = 0, f y (x, y) = 0. Since a critical point (x 0 , y 0 ) is a solution to both equations, both partial derivatives ...

Remark. A proof of the Second Derivative Test is rather involved. But there are two fundamental steps in it : the quadratic approximation of a function near a point (otherwise called the Taylor polynomial of degree 2) and the Second Derivative Test for quadratic functions. These two facts are...

Second Derivative TestTranscript We already know that setting a function f(x)f(x) equal to zero and solving will give us the xx-intercepts for that function. We also know that setting the derivative, f′(x)f′(x), equal to zero and solving will give us the points where the function...
