  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    Functions of a single variable (such as sine and cosine) may be implemented by a simple array. Functions involving two or more variables require multidimensional array indexing techniques. The latter case may thus employ a two-dimensional array of power[x][y] to replace a function to calculate x y for a limited range of x and y values ...

    In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using Excel. Because the sum in the second line has only eleven 1's after the decimal, the difference when 1 is subtracted from this displayed value is three 0's followed by a string of eleven 1's.

    The cell contents are not changed by this format, only the displayed value. Some cell formats such as "numeric" or "currency" can also specify the number of decimal places. This can allow invalid operations (such as doing multiplication on a cell containing a date), resulting in illogical results without an appropriate warning.

  5. Cut, copy, and paste - Wikipedia

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

    Inspired by early line and character editors, such as Pentti Kanerva's TV-Edit, [4] that broke a move or copy operation into two steps—between which the user could invoke a preparatory action such as navigation—Lawrence G. "Larry" Tesler proposed the names "cut" and "copy" for the first step and "paste" for the second step.

    Diffuse large B-cell lymphoma associated with chronic inflammation (DLBCL-CI) is a subtype of the Diffuse large B-cell lymphomas and a rare form of the Epstein–Barr virus-associated lymphoproliferative diseases, i.e. conditions in which lymphocytes infected with the Epstein-Barr virus (EBV) proliferate excessively in one or more tissues.

  7. Probability distribution - Wikipedia

    en.wikipedia.org/wiki/Probability_distribution

    Probability distributions usually belong to one of two classes. A discrete probability distribution is applicable to the scenarios where the set of possible outcomes is discrete (e.g. a coin toss, a roll of a die) and the probabilities are encoded by a discrete list of the probabilities of the outcomes; in this case the discrete probability ...

    [b] This meant that a date such as 29 January, while being toward the end of a legal year, would also be near the beginning of the following "common" (and Scottish) year. It was to show this duality that the system of displaying two year numbers first came into use — examples may be seen on memorial tablets and in parish registers.

  9. Line–line intersection - Wikipedia

    en.wikipedia.org/wiki/Lineline_intersection

    Assume that we want to find intersection of two infinite lines in 2-dimensional space, defined as a 1 x + b 1 y + c 1 = 0 and a 2 x + b 2 y + c 2 = 0. We can represent these two lines in line coordinates as U 1 = (a 1, b 1, c 1) and U 2 = (a 2, b 2, c 2). The intersection P′ of two lines is then simply given by [4]
