  2. Vector field - Wikipedia

    en.wikipedia.org/wiki/Vector_field

    hide. A portion of the vector field (sin y, sin x) In vector calculus and physics, a vector field is an assignment of a vector to each point in a space, most commonly Euclidean space . [ 1 ] A vector field on a plane can be visualized as a collection of arrows with given magnitudes and directions, each attached to a point on the plane.

  3. Phase plane - Wikipedia

    en.wikipedia.org/wiki/Phase_plane

    The phase plane method refers to graphically determining the existence of limit cycles in the solutions of the differential equation. The solutions to the differential equation are a family of functions. Graphically, this can be plotted in the phase plane like a two-dimensional vector field. Vectors representing the derivatives of the points ...

  4. Vector calculus - Wikipedia

    en.wikipedia.org/wiki/Vector_calculus

    Vector calculus or vector analysis is a branch of mathematics concerned with the differentiation and integration of vector fields, primarily in three-dimensional Euclidean space, . [1] The term vector calculus is sometimes used as a synonym for the broader subject of multivariable calculus, which spans vector calculus as well as partial differentiation and multiple integration.

  5. Attractor - Wikipedia

    en.wikipedia.org/wiki/Attractor

    Visual representation of a strange attractor. [1] Another visualization of the same 3D attractor is this video.Code capable of rendering this is available.. In the mathematical field of dynamical systems, an attractor is a set of states toward which a system tends to evolve, [2] for a wide variety of starting conditions of the system.

  6. Divergence - Wikipedia

    en.wikipedia.org/wiki/Divergence

    The divergence of a vector field F(x) at a point x0 is defined as the limit of the ratio of the surface integral of F out of the closed surface of a volume V enclosing x0 to the volume of V, as V shrinks to zero. where |V| is the volume of V, S(V) is the boundary of V, and is the outward unit normal to that surface.

  7. Divergence theorem - Wikipedia

    en.wikipedia.org/wiki/Divergence_theorem

    Mathematical analysis. Nonstandard analysis. v. t. e. In vector calculus, the divergence theorem, also known as Gauss's theorem or Ostrogradsky's theorem, [ 1 ] is a theorem relating the flux of a vector field through a closed surface to the divergence of the field in the volume enclosed.

  8. Spherical coordinate system - Wikipedia

    en.wikipedia.org/wiki/Spherical_coordinate_system

    In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a given point in space is specified by three real numbers: the radial distance r along the radial line connecting the point to the fixed point of origin; the polar angle θ between the radial line and a given polar axis; [a ...

  9. Helmholtz decomposition - Wikipedia

    en.wikipedia.org/wiki/Helmholtz_decomposition

    Definition. For a vector field defined on a domain , a Helmholtz decomposition is a pair of vector fields and such that: Here, is a scalar potential, is its gradient, and is the divergence of the vector field . The irrotational vector field is called a gradient field and is called a solenoidal field or rotation field.
