Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
Flat (geometry) In geometry, a flat or affine subspace is a subset of an affine space that is itself an affine space (of equal or lower dimension ). In the case the parent space is Euclidean, a flat is a Euclidean subspace which inherits the notion of distance from its parent space. The flats in a plane (two-dimensional space) are points, lines ...
Proportion (mathematics) A proportion is a mathematical statement expressing equality of two ratios. [ 1][ 2] a and d are called extremes, b and c are called means . Proportion can be written as , where ratios are expressed as fractions . Such a proportion is known as geometrical proportion, [ 3] not to be confused with arithmetical proportion ...
Linear algebra is the branch of mathematics concerning linear equations such as: linear maps such as: and their representations in vector spaces and through matrices. [ 1][ 2][ 3] Linear algebra is central to almost all areas of mathematics. For instance, linear algebra is fundamental in modern presentations of geometry, including for defining ...
Eating a balanced, nutrient-dense diet is key to a flat stomach, but knowing specific items that may affect this can help you feel more prepared in your goals.The following list of "worst foods ...
Take a look below. 1) More crunches equal a flatter tummy. The truth is that everyone has ab muscles that stay hidden underneath a thick layer of fat. The key is to focus on burning fat. 2 ...
A function f of x, differentiated once in Lagrange's notation. One of the most common modern notations for differentiation is named after Joseph Louis Lagrange, even though it was actually invented by Euler and just popularized by the former. In Lagrange's notation, a prime mark denotes a derivative.
Slope. Slope: In mathematics, the slope or gradient of a line is a number that describes the direction and steepness of the line. [ 1] Often denoted by the letter m, slope is calculated as the ratio of the vertical change to the horizontal change ("rise over run") between two distinct points on the line, giving the same number for any choice of ...
