Fluents

The problem of determining a tangent to a curve is transformed into the problem of finding the relationship between the fluxions x· and z· when presented with an equation representing the relationship between the fluents x and z. ❋ Bell, John L. (2009)

(A quadrature is the inverse problem, that of determining the fluents when the fluxions are given.) ❋ Bell, John L. (2009)

Am skeerd to post here cuz aim not fluents in Lol BUT I AM VEEERY fluents in SUGARGLIDER! ❋ Unknown (2008)

In fact, it is generally supposed that the domain of fluents will be a very limited set of the totality of situation-dependent functions; typically, it will be a relatively small finite set of important variables, and will be chosen in particular cases much as a set of variables is chosen in statistical modeling. ❋ Thomason, Richmond (2008)

Recall that fluents are represented as first-order individuals. ❋ Thomason, Richmond (2008)

In Baker's reformulation of the problem, separate axioms ensure the existence of a situation corresponding to each Boolean combination of fluents, and the RESULT function is allowed to vary, while the Holds predicate is held constant. ❋ Thomason, Richmond (2008)

And certain propositions whose truth values can change over time (propositional fluents) are also treated as individuals. ❋ Thomason, Richmond (2008)

I will describe four approaches here: (1) Features and fluents ❋ Thomason, Richmond (2008)

He further developed the calculus in Methodus fluxionum et serierum infinitarum (1671, published 1736), using as fundamental notions “fluxions” (time derivatives) and “fluents” (inverse of fluxions), fluents being interpreted as areas. ❋ Unknown (2001)

He had written his essay on fluxions, described their application to fluents and tangents, and devised a plan for finding the radius of curvity in crooked lines. ❋ Elbert Hubbard (1885)

Thus, the fluents of all fluxions under any of these forms may be found* ❋ Samuel Vince (1812)

Va W 2 + d* and taking the terms separately, the fluents of those terms where the index of x in the numerator is odd are found by Art. 41.; and where they are even by Art. 127. ❋ Unknown (1812)
