The plus sign + (itself based on an et-ligature) is often informally used in place of an ampersand, sometimes with an added loop and resembling ɬ. [citation needed] Other times it is a single stroke with a diagonal line connecting the bottom to the left side. This was a version of shorthand for ampersand, and the stroke economy of this version ...
Vector notation. Describing an arrow vector v by its coordinates x and y yields an isomorphism of vector spaces. In mathematics and physics, vector notation is a commonly used notation for representing vectors, [1] [2] which may be Euclidean vectors, or more generally, members of a vector space .
The £ grapheme in a selection of fonts. The pound sign ( £) is the symbol for the pound unit of sterling – the currency of the United Kingdom and its associated Crown Dependencies and British Overseas Territories and previously of Great Britain and of the Kingdom of England. The same symbol is used for other currencies called pound, such as ...
For transparency, consensus-building purposes, I wish to make editors aware that I have added the purple box, with "±" depicted, to the article ().If there are any qualms or enquiries regarding my change, please feel free to discuss with me on my talk page, or below (NB, you might wish to drop me a note of any discussion ongoing here, at my talk page).
cis (mathematics) cis is a mathematical notation defined by cis x = cos x + i sin x, [nb 1] where cos is the cosine function, i is the imaginary unit and sin is the sine function. x is the argument of the complex number (angle between line to point and x-axis in polar form ). The notation is less commonly used in mathematics than Euler's ...
Ditto mark. The ditto mark is a shorthand sign, used mostly in hand-written text, indicating that the words or figures above it are to be repeated. [1] [2] The mark is made using "a pair of apostrophes "; [1] "a pair of marks " used underneath a word"; [3] the symbol " ( quotation mark ); [2] [4] or the symbol ” (right double quotation mark). [5]
In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 10 3, the logarithm base of 1000 is 3, or log 10 (1000) = 3.
Scalar (mathematics) A scalar is an element of a field which is used to define a vector space . In linear algebra, real numbers or generally elements of a field are called scalars and relate to vectors in an associated vector space through the operation of scalar multiplication (defined in the vector space), in which a vector can be multiplied ...
