Ampersand: the sign &; the name being a corruption of 'and per se = and'; i.e. ' & by itself = and'. The sign derives from the scribes' ligature for the Latin: et; in certain italic versions, the letters e and t are clearly distinguishable.
Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [ 2][ 3]
f ′ ( x) 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.
The conventional symbols for the signs of the zodiac also develop in the Renaissance period as simplifications of the classical pictorial representations of the signs.) [citation needed] The modern sun symbol resembles the Egyptian hieroglyph for "sun" – a circle that sometimes had a dot in the center, (U+131F3 ㇳ EGYPTIAN HIEROGLYPH N005).
propositional logic, Boolean algebra, first-order logic. ⊥ {\displaystyle \bot } denotes a proposition that is always false. The symbol ⊥ may also refer to perpendicular lines. The proposition. ⊥ ∧ P {\displaystyle \bot \wedge P} is always false since at least one of the two is unconditionally false. ∀.
The character ∂ ( Unicode: U+2202) is a stylized cursive d mainly used as a mathematical symbol, usually to denote a partial derivative such as (read as "the partial derivative of z with respect to x "). [ 1][ 2] It is also used for boundary of a set, the boundary operator in a chain complex, and the conjugate of the Dolbeault operator on ...
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
In astronomy , it stands for the fifth-brightest star in a constellation (see Bayer designation ). Epsilon is the name for the most distant and most visible ring of Uranus. In planetary science, ε denotes the axial tilt. In chemistry, it represents the molar extinction coefficient of a chromophore.
