  3. Regula falsi - Wikipedia

    en.wikipedia.org/wiki/Regula_falsi

    A value c that satisfies this equation, that is, f (c) = 0, is called a root or zero of the function f and is a solution of the original equation. If f is a continuous function and there exist two points a 0 and b 0 such that f ( a 0 ) and f ( b 0 ) are of opposite signs, then, by the intermediate value theorem , the function f has a root in ...

  4. Formula editor - Wikipedia

    en.wikipedia.org/wiki/Formula_editor

    A formula editor is a computer program that is used to typeset mathematical formulas and mathematical expressions. Formula editors typically serve two purposes: They allow word processing and publication of technical content either for print publication, or to generate raster images for web pages or screen presentations.

  5. Rule of 72 - Wikipedia

    en.wikipedia.org/wiki/Rule_of_72

    The formula above can be used for more than calculating the doubling time. If one wants to know the tripling time, for example, replace the constant 2 in the numerator with 3. As another example, if one wants to know the number of periods it takes for the initial value to rise by 50%, replace the constant 2 with 1.5.

  6. Mathematics of paper folding - Wikipedia

    en.wikipedia.org/wiki/Mathematics_of_paper_folding

    Wet-folding origami is a technique evolved by Yoshizawa that allows curved folds to create an even greater range of shapes of higher order complexity. The maximum number of times an incompressible material can be folded has been derived. With each fold a certain amount of paper is lost to potential folding.

  7. Pythagorean expectation - Wikipedia

    Initially the correlation between the formula and actual winning percentage was simply an experimental observation. In 2003, Hein Hundal provided an inexact derivation of the formula and showed that the Pythagorean exponent was approximately 2/(σ √ π) where σ was the standard deviation of runs scored by all teams divided by the average number of runs scored.

  9. Euler method - Wikipedia

    en.wikipedia.org/wiki/Euler_method

    The backward Euler method is an implicit method, meaning that the formula for the backward Euler method has + on both sides, so when applying the backward Euler method we have to solve an equation. This makes the implementation more costly.
