Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.

In solid mechanics and structural engineering, section modulus is a geometric property of a given cross-section used in the design of beams or flexural members.Other geometric properties used in design include: area for tension and shear, radius of gyration for compression, and second moment of area and polar second moment of area for stiffness.
Angular field of view is typically specified in degrees, while linear field of view is a ratio of lengths. For example, binoculars with a 5.8 degree (angular) field of view might be advertised as having a (linear) field of view of 102 mm per meter. As long as the FOV is less than about 10 degrees or so, the following approximation formulas ...
Parameters of a stadium The Bunimovich stadium, a chaotic dynamical system based on the stadium shape The bottom of this plastic basket is stadium-shaped.. A stadium is a two-dimensional geometric shape constructed of a rectangle with semicircles at a pair of opposite sides. [1]
In linear algebra, the Hermite normal form is an analogue of reduced echelon form for matrices over the integers.Just as reduced echelon form can be used to solve problems about the solution to the linear system = where , the Hermite normal form can solve problems about the solution to the linear system = where this time is restricted to have integer coordinates only.
In electromagnetism, the electromagnetic tensor or electromagnetic field tensor (sometimes called the field strength tensor, Faraday tensor or Maxwell bivector) ...
When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to Faraday's law of induction. The current in the wire can have two possible directions. Fleming's right-hand rule gives which direction the current flows.
The complex is in the Mt Kendang area, where 2000 meters above ocean level on the volcanic mountains. The Darajat geothermal field is a generous excellent asset delivering dry steam at the wellhead. The asset is one of just a couple of dry steam fields on the planet. [1]
