  2. Involute - Wikipedia

    en.wikipedia.org/wiki/Involute

    In mathematics, an involute (also known as an evolvent) is a particular type of curve that is dependent on another shape or curve. An involute of a curve is the locus of a point on a piece of taut string as the string is either unwrapped from or wrapped around the curve. [1] The evolute of an involute is the original curve.

  3. Involution (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Involution_(mathematics)

    An involution is a function f : X → X that, when applied twice, brings one back to the starting point. In mathematics, an involution, involutory function, or self-inverse function [1] is a function f that is its own inverse, f(f(x)) = x. for all x in the domain of f. [2] Equivalently, applying f twice produces the original value.

  4. Tractrix - Wikipedia

    en.wikipedia.org/wiki/Tractrix

    The function admits a horizontal asymptote. The curve is symmetrical with respect to the y-axis. The curvature radius is r = a cot ⁠ x / y ⁠. A great implication that the tractrix had was the study of its surface of revolution about its asymptote: the pseudosphere.

    en.wikipedia.org/wiki/Logical_spreadsheet

    A logical spreadsheet is a spreadsheet in which formulas take the form of logical constraints rather than function definitions.. In traditional spreadsheet systems, such as Excel, cells are partitioned into "directly specified" cells and "computed" cells and the formulas used to specify the values of computed cells are "functional", i.e. for every combination of values of the directly ...

    en.wikipedia.org/wiki/OpenFormula

    Innovations from many sources: OpenFormula covers the functions of Excel and OpenOffice.org, plus important functions not found in either one but instead found in other spreadsheet applications, such as Gnumeric and KSpread. For example, the specification includes the functions DECIMAL and BASE, which are much better ways to handle different ...
