    1. The technique of shooting a widescreen picture on visual recording media with a non-widescreen native aspect ratio. 2. A projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen. anamorphic widescreen angle of light angle of view angle plus angle

    In calculus there are two sections, one is differentiation and the other is integration. Integration is the reverse process of differentiation. [1] See also ...

    en.wikipedia.org/wiki/Derivative

    The process of finding a derivative is called differentiation. There are multiple different notations for differentiation. Leibniz notation , named after Gottfried Wilhelm Leibniz , is represented as the ratio of two differentials , whereas prime notation is written by adding a prime mark .

  6. Notation for differentiation - Wikipedia

    en.wikipedia.org/wiki/Notation_for_differentiation

    Isaac Newton's notation for differentiation (also called the dot notation, fluxions, or sometimes, crudely, the flyspeck notation [12] for differentiation) places a dot over the dependent variable. That is, if y is a function of t, then the derivative of y with respect to t is ˙

  7. Power rule - Wikipedia

    en.wikipedia.org/wiki/Power_rule

    The exclusion of the expression (the case =) from our scheme of exponentiation is due to the fact that the function (,) = has no limit at (0,0), since approaches 1 as x approaches 0, while approaches 0 as y approaches 0. Thus, it would be problematic to ascribe any particular value to it, as the value would contradict one of the two cases ...

  8. Differential of a function - Wikipedia

    en.wikipedia.org/wiki/Differential_of_a_function

    the partial differential of y with respect to any one of the variables x 1 is the principal part of the change in y resulting from a change dx 1 in that one variable. The partial differential is therefore involving the partial derivative of y with respect to x 1.

    Gottfried Wilhelm von Leibniz (1646–1716), German philosopher, mathematician, and namesake of this widely used mathematical notation in calculus.. In calculus, Leibniz's notation, named in honor of the 17th-century German philosopher and mathematician Gottfried Wilhelm Leibniz, uses the symbols dx and dy to represent infinitely small (or infinitesimal) increments of x and y, respectively ...
