High order partial derivative
WebAug 2, 2024 · $\begingroup$ @KeshavSrinivasan the reason people are saying the higher-order derivative test you found is not in the same spirit as the 2nd-derivative test is that the 2nd-derivative test is a numerical test: there are standard algorithms to determine if a quadratic form is positive definite, negative definite, or indefinite. The test you found … WebJan 26, 2024 · Higher Partial Derivatives But what about higher partial derivatives? Yes, we can find higher order partial derivatives. In fact, there are four possibilities for the second partial derivative for a function of two variables Differentiate twice with respect to x: ∂ ∂ x ( ∂ f ∂ x) = ∂ 2 f ∂ x 2 = f x x Differentiate twice with respect to y:
