by 1.3 × 10 −11 and the 16-point Gaussian quadrature rule estimate of 1.570 796 326 794 727 differs from the true length by only 1.7 × 10 −13. This means it is possible to evaluate this integral to almost machine precision with only 16 integrand evaluations.
In mathematical analysis, the staircase paradox is a pathological example showing that limits of curves do not necessarily preserve their length. [1] It consists of a sequence of "staircase" polygonal chains in a unit square , formed from horizontal and vertical line segments of decreasing length, so that these staircases converge uniformly to ...
The resulting modified natural continuation method makes a step in pseudo-arclength (rather than ). The iterative solver is required to find a point at the given pseudo-arclength, which requires appending an additional constraint (the pseudo-arclength constraint) to the n by n+1 Jacobian.
The arc length of an involute is given by so the arc length |FG| of the involute in the fourth quadrant is []. Let c be the length of an arc segment of the involute between the y -axis and a vertical line tangent to the silo at θ = 3 π /2; it is the arc subtended by Φ .
Shortest path (A, C, E, D, F), blue, between vertices A and F in the weighted directed graph. In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized.
The circle itself is characterized by coordinates y 1 and y 2 in the two-dimensional space. The circle itself is one-dimensional and can be characterized by its arc length x. The coordinate y is related to the coordinate x through the relation y 1 = r cos x / r and y 2 = r sin x / r .
Therefore, it is possible to solve for t as a function of s, and thus to write r(s) = r(t(s)). The curve is thus parametrized in a preferred manner by its arc length. With a non-degenerate curve r(s), parameterized by its arc length, it is now possible to define the Frenet–Serret frame (or TNB frame):
Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude. This distance is an element in solving the second (inverse) geodetic ...
