and then computing the dot product of this with the given unit vector: Duf(x0,y0)=∇f(x0,y0)⋅u→ If the directional derivative of a function at a point is zero in a certain direction, then the unit vector must be perpendicular to the gradient at this...
What is the gradient of h(x,y)=ycos(x−y) and the maximum value of the directional derivative at (0,π3)? Gradient: For a function f(x,y) at (a,b), the gradient is defined as fx(a,b)i^+fy(a,b)j^. The directional derivative in t...
As it is shown in the first part of this short essay, duality plus conservation laws allow the violation of Bell’s inequalities for any spatio-temporal separation. To dig deeper into particle dualism, in the second part, a class of models is proposed as a working framework. It encompasses...
DF_x (U) is the directional derivative of F in the direction of U. But I don't understand what this definition means?ThanksPhysics news on Phys.org Controlling quantum motion and hyper-entanglement A new nanometer-scale measurement tool exploits the quantum properties of light for better ...

Quantum reality has a reversible nature, so the entropy of the system is constant and therefore its description is an invariant. The space-time synchronization of events requires an intimate connection of space-time at the level of quantum reality, which is deduced from the theory of relativity ...

Since the curve is a group of transformations, the directional derivative at [itex] (x,y) [/itex] is determined by what the transformation does to the point [itex] (x,y) [/itex] by values of [itex] \alpha [/itex] close to zero. I'd think that some advanced calculus book so...
a snapshot of the model (but I can do way less with only a picture).And now I understand what the error message is trying to say about time derivative: when you try to divide the force by the mass to get acceleration (derivative of velocity) but ...
a manifold) X, and v is a tangent vector to X at some point x, we can define the directional derivative of f at x by comparing with for some infinitesimal dt, take the difference , divide by dt, and then take limits as : . [Strictly speaking, if X is not flat, then x+vdt is...
