WebAnswer (1 of 2): According to Wolfram MathWorld, “A necessary condition for x to be an inflection point is f^{''}(x)=0.” Therefore, if the second derivative does not exist, it cannot be formally identified as an inflection point. Wolfram also mentions that a sufficient condition for x to be an i... WebWhat we may have, is that if we have twice differentiable functions and in particular when they are just the single varied, if we say they are twice differentiable, which means the second-order derivative exist, then we have Proposition 6, which is quite useful.
WebSecond derivative is greater than zero. And so this intuition that we hopefully just built up is what the second derivative test tells us. So it says hey look, if we're dealing with some … WebMar 13, 2024 · Explanation: If \(f\) is twice continuously differentiable, then its second derivatives are independent of the order in which the derivatives are applied. All the terms cancel in the expression for curl \(\triangledown f\), and we conclude that \(\triangledown f = 0\). Divergence operates on a vector field but results in a scalar.; Curl operates on a …
WebHow I originally thought of it was to find an odd function which takes $0$ at $0$ so that the top is simultaneously zero--but cook up that the function was not twice differentiable. I …
