  2. Formula for change - Wikipedia

    en.wikipedia.org/wiki/Formula_for_change

    The formula for change (or "the change formula") provides a model to assess the relative strengths affecting the likely success of organisational change programs. The formula was created by David Gleicher while he was working at management consultants Arthur D. Little in the early 1960s, [1] refined by Kathie Dannemiller in the 1980s, [2] and further developed by Steve Cady.

    Example: The final value of a 7-year annuity-due with a nominal annual interest rate of 9% and monthly payments of $100 can be calculated by: FV due ( 0.09 12 , 7 × 12 , $ 100 ) = $ 100 × s ¨ 84 ¯ | 0.0075 = $ 11 , 730.01. {\displaystyle {\text{FV}}_{\text{due}}\left({\frac {0.09}{12}},7\times 12,\$100\right)=\$100\times {\ddot {s ...

    For example, instead of A function f is even if and only if f(−x) = f(x) for all x; write A function f is even if f(−x) = f(x) for all x. If it is reasonable to do so, rephrase the sentence to avoid the use of the word "if" entirely. For example, An even function is a function f such that f(−x) = f(x) for all x

    An example is boron carbide, whose formula of CB n is a variable non-whole number ratio, with n ranging from over 4 to more than 6.5. When the chemical compound of the formula consists of simple molecules, chemical formulas often employ ways to suggest the structure of the

    It is assumed that the value of a function f defined on [,] is known at + equally spaced points: < < <.There are two classes of Newton–Cotes quadrature: they are called "closed" when = and =, i.e. they use the function values at the interval endpoints, and "open" when > and <, i.e. they do not use the function values at the endpoints.

  7. Ordinary least squares - Wikipedia

    en.wikipedia.org/wiki/Ordinary_least_squares

    In statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one [clarification needed] effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed dependent variable (values ...

  8. Viète's formula - Wikipedia

    en.wikipedia.org/wiki/Viète's_formula

    Viète's formula may be rewritten and understood as a limit expression [3] = =, where = = +.. For each choice of , the expression in the limit is a finite product, and as gets arbitrarily large, these finite products have values that approach the value of Viète's formula arbitrarily closely.
