In mathematics, a singularity is a point at which a given mathematical object is not defined, or a point where the mathematical object ceases to be well-behaved in some particular way, such as by lacking differentiability or analyticity.
Central Antenna: In the middle of the choke ring structure is a tiny, high-gain antenna. The GNSS signals must be received by this antenna. Concentric Cylinders: These devices are intended to block transmissions that originate below the horizon.
Singularity (system theory), in dynamical and social systems, a context in which a small change can cause a large effect Gravitational singularity, in general relativity, a point in which gravity is so intense that spacetime itself becomes ill-defined
Singular homology; SINGULAR, an open source Computer Algebra System (CAS); Singular matrix, a matrix that is not invertible; Singular measure, a measure or probability distribution whose support has zero Lebesgue (or other) measure
A selection of cubic curves. Click the image to see information page for details. In mathematics, a cubic plane curve is a plane algebraic curve C defined by a cubic equation
The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system. [1]They can also represent the orientation of a mobile frame of reference in physics or the orientation of a general basis in three dimensional linear algebra.
A central feature of smooth cubic surfaces X over an algebraically closed field is that they are all rational, as shown by Alfred Clebsch in 1866. [1] That is, there is a one-to-one correspondence defined by rational functions between the projective plane minus a lower-dimensional subset and X minus a lower-dimensional subset.
Graphs of curves y 2 = x 3 − x and y 2 = x 3 − x + 1. Although the formal definition of an elliptic curve requires some background in algebraic geometry, it is possible to describe some features of elliptic curves over the real numbers using only introductory algebra and geometry.
