SD. Second Derivative Test - MIT Mathematics SD. SECOND DERIVATIVE TEST 3 Argument for the Second-derivative Test for a general function. This part won’t be rigorous, only suggestive, but it will give the right idea. We consider a general function w= f(x,y), and assume it has a critical point at (x0
How do I test for a saddle point when the second derivative test fails? How do I test for a saddle point when the second derivative test fails?

Second derivative test - Wikipedia, the free encyclopedia In calculus, the second derivative test is a criterion for determining whether a given critical point of a real function of one variable is a local maximum or a local minimum using the value of the second derivative at the point. The test states: if the f
