Paraxial approximation — In geometric optics, the paraxial approximation is an approximation used in ray tracing of light through an optical system (such as a lens).cite book | first=John E. | last=Greivenkamp | year=2004 | title=Field Guide to Geometrical Optics |… … Wikipedia
Boussinesq approximation (buoyancy) — In fluid dynamics, the Boussinesq approximation (named for Joseph Valentin Boussinesq) is used in the field of buoyancy driven flow (also known as natural convection). It states that density differences are sufficiently small to be neglected,… … Wikipedia
Generating trigonometric tables — In mathematics, tables of trigonometric functions are useful in a number of areas. Before the existence of pocket calculators, trigonometric tables were essential for navigation, science and engineering. The calculation of mathematical tables was … Wikipedia
MATHEMATICS — Bible The Bible does not deal directly with proper mathematical subjects; however there are some parts that do relate indirectly to different mathematical topics. These are widely discussed by the various commentators on the Bible and Talmud: the … Encyclopedia of Judaism
Sobel operator — The Sobel operator is used in image processing, particularly within edge detection algorithms. Technically, it is a discrete differentiation operator, computing an approximation of the gradient of the image intensity function. At each point in… … Wikipedia
Image gradient — In graphics software for digital image editing, the term gradient is used for a gradual blend of colour which can be considered as an even gradation from low to high values, as used from white to black in the images to the right.Mathematically,… … Wikipedia
Numeric precision in Microsoft Excel — As with other spreadsheets, Microsoft Excel works only to limited accuracy because it retains only a certain number of figures to describe numbers (it has limited precision). Excel nominally works with 8 byte numbers by default, a modified 1985… … Wikipedia
