51Normal distribution — This article is about the univariate normal distribution. For normally distributed vectors, see Multivariate normal distribution. Probability density function The red line is the standard normal distribution Cumulative distribution function …
52Complex conjugate — Geometric representation of z and its conjugate in the complex plane In mathematics, complex conjugates are a pair of complex numbers, both having the same real part, but with imaginary parts of equal magni …
53Sinusoidal projection — The sinusoidal projection is a pseudocylindrical equal area map projection, sometimes called the Sanson Flamsteed or the Mercator equal area projection. It is defined by::x = left(lambda lambda 0 ight) cos phi:y = phi,where phi, is the latitude,… …
54Dirac delta function — Schematic representation of the Dirac delta function by a line surmounted by an arrow. The height of the arrow is usually used to specify the value of any multiplicative constant, which will give the area under the function. The other convention… …
55List of canonical coordinate transformations — This is a list of canonical coordinate transformations. 2 DimensionalLet (x, y) be the standard Cartesian coordinates, and r and θ the standard polar coordinates.To Cartesian coordinates from polar coordinates:x=r,cos heta quad:y=r,sin heta… …
56Circular distribution — In probability and statistics, a circular distribution or polar distribution is a probability distribution of a random variable whose values are angles, usually taken to be in the range [ 0,  2π ) .[1] A circular distribution is… …
57Cos4-Gesetz — Helligkeitsabfall für verschiedene Brennweiten, bezogen auf das Kleinbildformat (43,2 mm Diagonale) Das Cos4 Gesetz (lies: Kosinus hoch 4 Gesetz) beschreibt den natürlichen Randlichtabfall. Es besagt, dass die Bildhelligkeit beim Abbilden… …
58Misorientation — is the difference in crystallographic orientation between two crystallites in a polycrystalline material. In crystalline materials, the orientation of a crystallite is defined by a transformation from a sample reference frame (i.e. defined by the …
59Flight dynamics — is the science of air and space vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle s center of mass, known as pitch , roll and yaw… …
60Associated Legendre function — Note: This article describes a very general class of functions. An important subclass of these functions mdash;those with integer ell and m mdash;are commonly called associated Legendre polynomials , even though they are not polynomials when m is …
