In transport phenomena, flux is a vector quantity. It describes the flow’s magnitude and direction for a property or substance. In vector calculus, flux is a scalar quantity. It is defined as the surface integral of a vector field’s perpendicular component over a surface. The word “Flux...
. However, in this set of notes we will not develop the spectral theory necessary in order to fully set out this functional calculus rigorously. In the field of PDE and ODE, it is also very common to studyvariable coefficientlinear differential operators ...
A vector field is exact if it is the derivative (gradient) of some scalar function. That is, if V is a vector field, and f is any scalar function that solves the equation V=∇f, then we say that V is exact. It is a theorem in each text on vector calculus that every closed ve...

When getting started with machine learning, developers will rely on their knowledge of statistics, probability, and calculus to most successfully create models that learn over time. With sharp skills in these areas, developers should have no problem learning the tools many other developers use to tr...
1914:Mathematician and inventor Leonardo Torres y Quevedo debuts "El Ajedrecista," an automaton that can play chess and defeat human players in certain circumstances. 1943:Neurophysiologist Warren McCulloch and mathematician Walter Pitts publish "A Logical Calculus of the Ideas Imminent in Nervous Acti...
What Is a Gradient? A gradient is a derivative of a function that has more than one input variable. It is a term used to refer to the derivative of a function from the perspective of the field of linear algebra. Specifically when linear algebra meets calculus, called vector calculus. The...

azimuths can be used for more than just navigation. In general, the term azimuth can refer to any angle which is measured between the projection of the vector from the origin to a point of interest on a (horizontal) reference plane, and the chosen reference vector in that plane. The azim...
In vector calculus, the gradient of a scalar-valued differentiable function f of several variables is the vector field (or vector-valued function) ∇ f {\displaystyle \nabla f} whose value at a point p {\displaystyle p} is the vector whose components are the partial derivatives of f {\...
