    In mathematics, osculate, meaning to touch (from the Latin osculum meaning kiss), may refer to: osculant, an invariant of hypersurfaces; osculating circle; osculating curve ...

  3. Oscillation - Wikipedia

    en.wikipedia.org/wiki/Oscillation

    An undamped spring–mass system is an oscillatory system. Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states.

  4. Osculating orbit - Wikipedia

    en.wikipedia.org/wiki/Osculating_orbit

    Osculating orbit (inner, black) and perturbed orbit (red) In astronomy, and in particular in astrodynamics, the osculating orbit of an object in space at a given moment in time is the gravitational Kepler orbit (i.e. an elliptic or other conic one) that it would have around its central body if perturbations were absent.

  5. Osculating plane - Wikipedia

    en.wikipedia.org/wiki/Osculating_plane

    A space curve, Frenet–Serret frame, and the osculating plane (spanned by T and N). In mathematics, particularly in differential geometry, an osculating plane is a plane in a Euclidean space or affine space which meets a submanifold at a point in such a way as to have a second order of contact at the point.

    By definition, it is the amount of energy gained by the charge of a single electron moved across an electric potential difference of one volt. electronegativity A chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself. electronics

  7. Pax (liturgical object) - Wikipedia

    en.wikipedia.org/wiki/Pax_(liturgical_object)

    [a] Osculatory is used in some 19th-century sources, [5] and some claim that this refers to a pendant form, worn round the neck by the priest. This does not appear in most modern scholarship, though given a one-line entry by Oxford Art Online. [6] Translators unfamiliar with the concept may introduce still further names into English.

    root mean square The root mean square value of a waveform is the DC value that corresponds to equivalent heating value. rotary converter An electric machine that converts electric power between two forms, say, AC and DC or single-phase and three phase, or between two different frequencies of AC (the latter two can be performed by the same machine).

  9. Oscillation (mathematics) - Wikipedia

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

    Oscillation of a sequence (shown in blue) is the difference between the limit superior and limit inferior of the sequence. In mathematics, the oscillation of a function or a sequence is a number that quantifies how much that sequence or function varies between its extreme values as it approaches infinity or a point.
