  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    One good solution is linear interpolation, which draws a line between the two points in the table on either side of the value and locates the answer on that line. This is still quick to compute, and much more accurate for smooth functions such as the sine function.

  3. Spreadsheet - Wikipedia

    en.wikipedia.org/wiki/Spreadsheet

    When the computer calculates a formula in one cell to update the displayed value of that cell, cell reference(s) in that cell, naming some other cell(s), causes the computer to fetch the value of the named cell(s). A cell on the same "sheet" is usually addressed as: =A1 A cell on a different sheet of the same spreadsheet is usually addressed as:

  4. Linear multistep method - Wikipedia

    en.wikipedia.org/wiki/Linear_multistep_method

    This method needs two values, + and , to compute the next value, +. However, the initial value problem provides only one value, y 0 = 1 {\displaystyle y_{0}=1} . One possibility to resolve this issue is to use the y 1 {\displaystyle y_{1}} computed by Euler's method as the second value.

  5. Boolean satisfiability problem - Wikipedia

    en.wikipedia.org/wiki/Boolean_satisfiability_problem

    For example, the formula "a AND NOT b" is satisfiable because one can find the values a = TRUE and b = FALSE, which make (a AND NOT b) = TRUE. In contrast, " a AND NOT a " is unsatisfiable. SAT is the first problem that was proven to be NP-complete —this is the Cook–Levin theorem .

  6. Multivalued function - Wikipedia

    en.wikipedia.org/wiki/Multivalued_function

    In mathematics, a multivalued function, [1] multiple-valued function, [2] many-valued function, [3] or multifunction, [4] is a function that has two or more values in its range for at least one point in its domain. [5]

  7. Numbers (spreadsheet) - Wikipedia

    en.wikipedia.org/wiki/Numbers_(spreadsheet)

    Data is manipulated using formulas, which are placed in other cells in the same sheet and output their results back into the formula cell's display. The rest of the sheet is "sparse", and currently unused. [7] Sheets often grow very complex with input data, intermediate values from formulas, and output areas, separated by blank areas.

  8. Newton polynomial - Wikipedia

    en.wikipedia.org/wiki/Newton_polynomial

    Gauss's formula alternately adds new points at the left and right ends, thereby keeping the set of points centered near the same place (near the evaluated point). When so doing, it uses terms from Newton's formula, with data points and x values renamed in keeping with one's choice of what data point is designated as the x 0 data point.

  9. Gaussian quadrature - Wikipedia

    en.wikipedia.org/wiki/Gaussian_quadrature

    With the n-th polynomial normalized to give P n (1) = 1, the i-th Gauss node, x i, is the i-th root of P n and the weights are given by the formula [3] = [′ ()]. Some low-order quadrature rules are tabulated below (over interval [−1, 1] , see the section below for other intervals).
