Mathematically, a scalar field on a region U is a real or complex-valued function or distribution on U. The region U may be a set in some Euclidean space, Minkowski space, or more generally a subset of a manifold, and it is typical in mathematics to impose further conditions on the field, such that it be continuous or often continuously differentiable to some order. A scalar field is a tensor field of order zero, and the term "scalar field" may be used to distinguish a function of this kind with a m… WebCONSERVATIVE VECTOR FIELD A vector field F is called a conservative vector field if it is the gradient of some scalar function—that is, if there exists a function f such that F = . In this situation, f is called a potential function for F. Let’s assume that the object with mass M is located at the origin in R3.3. For instance, M

WebWhen you plot multiple inputs over different intervals in the same axes, the axis limits adjust to display all the data. This behavior lets you plot piecewise inputs.
