Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...
Restriction of a function: if f is a function, and S is a subset of its domain, then | is the function with S as a domain that equals f on S. 4. Conditional probability : P ( X ∣ E ) {\displaystyle P(X\mid E)} denotes the probability of X given that the event E occurs.
The continued fractions on the right hand side will converge uniformly on any closed and bounded set that contains no poles of this function. [ 7 ] In the case 2 F 1 {\displaystyle {}_{2}F_{1}} , the radius of convergence of the series is 1 and the fraction on the left hand side is a meromorphic function within this circle.
Nitryl fluoride, NO 2 F, is a colourless gas and strong oxidizing agent, which is used as a fluorinating agent [1] and has been proposed as an oxidiser in rocket propellants (though never flown).
The slash is a slanting line punctuation mark /.It is also known as a stroke, a solidus, a forward slash and several other historical or technical names.Once used to mark periods and commas, the slash is now used to represent division and fractions, exclusive 'or' and inclusive 'or', and as a date separator.
The Avogadro constant, commonly denoted N A [1] or L, [2] is an SI defining constant with an exact value of 6.022 140 76 × 10 23 mol −1 (reciprocal moles). [3] [4] It is this defined number of constituent particles (usually molecules, atoms, ions, or ion pairs—in general, entities) per mole and used as a normalization factor in relating the amount of substance, n(X), in a sample of a ...
Delta is the initial letter of the Greek word διαφορά, diaphorá, "difference". (The small Latin letter d is used in much the same way for the notation of derivatives and differentials, which also describe change by infinitesimal amounts.) The Laplace operator:
The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
