Explore: Line Element

In geometry, the line element or length element can be informally thought of as a line segment associated with an infinitesimal displacement vector in

A two-line element set (TLE, or more rarely 2LE) or three-line element set (3LE) is a data format encoding a list of orbital elements of an Earth-orbiting

ambiguous Fraunhofer line designations are preceded by the element with which they are associated (e.g., Mercury e line and Helium d line). Because of their

who was killed in the 1966 University of Texas tower shooting. The line element for a black hole with a total mass equivalent M {\displaystyle M} , angular

Euclidean geometry defines its line element as d s e 2 = d x 2 + d y 2 , {\displaystyle ds_{e}^{2}=dx^{2}+dy^{2},} the line element on Minkowski space is d s

ASCII records can be handled efficiently by modern databases. The two-line element format lists the eccentricity (e), inclination (i), longitude of the

loaded differential line element. It is defined as the ratio between the final length l and the initial length L of the material line. λ = l L {\displaystyle

In mathematics, a volume element provides a means for integrating a function with respect to volume in various coordinate systems such as spherical coordinates

from the positive z axis, as in the physics convention discussed. The line element for an infinitesimal displacement from (r, θ, φ) to (r + dr, θ + dθ,

many forms including the traditional Position-Velocity vectors, Two-line element set (TLE), and Vector Covariance Matrix (VCM). State vectors are defined
