  3. Function of several real variables - Wikipedia

    en.wikipedia.org/wiki/Function_of_several_real...

    The image of a function f(x 1, x 2, …, x n) is the set of all values of f when the n-tuple (x 1, x 2, …, x n) runs in the whole domain of f.For a continuous (see below for a definition) real-valued function which has a connected domain, the image is either an interval or a single value.

  4. Let expression - Wikipedia

    en.wikipedia.org/wiki/Let_expression

    The expression should be based on the variable and the set. Function application applied to this form should give another expression in the same form. In this way any expression on functions of multiple values may be treated as if it had one value. It is not sufficient for the form to represent only the set of values.

  5. Keyboard shortcut - Wikipedia

    en.wikipedia.org/wiki/Keyboard_shortcut

    In computing, a keyboard shortcut (also hotkey/hot key or key binding) [1] is a software-based assignment of an action to one or more keys on a computer keyboard. Most operating systems and applications come with a default set of keyboard shortcuts , some of which may be modified by the user in the settings .

  6. Multivalued function - Wikipedia

    en.wikipedia.org/wiki/Multivalued_function

    Multivalued functions of a complex variable have branch points. For example, for the nth root and logarithm functions, 0 is a branch point; for the arctangent function, the imaginary units i and −i are branch points. Using the branch points, these functions may be redefined to be single-valued functions, by restricting the range.

  7. Control-X - Wikipedia

    en.wikipedia.org/wiki/Control-X

    In computing, Control-X or ^X is the key combination of the control key and a key usually labelled "X", typically used to cut selected text and save it to the clipboard ready to paste elsewhere. There is some disagreement whether the action moves with the key labelled "X" or stays in the lower-left location on keyboards with different letter ...

  8. Macro (computer science) - Wikipedia

    en.wikipedia.org/wiki/Macro_(computer_science)

    The ability to use a familiar procedural language as the macro language gives power much greater than that of text substitution macros, at the expense of a larger and slower compiler. Macros in PL/I, as well as in many assemblers, may have side effects, e.g., setting variables that other macros can access.

  9. Cut, copy, and paste - Wikipedia

    en.wikipedia.org/wiki/Cut,_copy,_and_paste

    The user selects or "highlights" the text or file for moving by some method, typically by dragging over the text or file name with the pointing-device or holding down the Shift key while using the arrow keys to move the text cursor. The user performs a "cut" operation via key combination Ctrl+x (⌘+x for Macintosh users), menu, or other means.
