2. Methods of computing square roots - Wikipedia

   en.wikipedia.org/wiki/Methods_of_computing...

   If division is much more costly than multiplication, it may be preferable to compute the inverse square root instead. Other methods are available to compute the square root digit by digit, or using Taylor series . Rational approximations of square roots may be calculated using continued fraction expansions .

3. Fast inverse square root - Wikipedia

   en.wikipedia.org/wiki/Fast_inverse_square_root

   The fast inverse square root is used to generalize this calculation to three-dimensional space. The inverse square root of a floating point number is used in digital signal processing to normalize a vector, scaling it to length 1 to produce a unit vector. [14] For example, computer graphics programs use inverse square roots to compute angles of ...

4. Multiplication algorithm - Wikipedia

   en.wikipedia.org/wiki/Multiplication_algorithm

   Multiplication algorithm. A multiplication algorithm is an algorithm (or method) to multiply two numbers. Depending on the size of the numbers, different algorithms are more efficient than others. Efficient multiplication algorithms have existed since the advent of the decimal numeral system .

   2. Decide your ideal macronutrient breakdown. After determining how many calories to consume each day, the next step is to decide what macronutrient ratio works best for you. Typical macronutrient ...

7. Trachtenberg system - Wikipedia

   en.wikipedia.org/wiki/Trachtenberg_system

   Trachtenberg system. The Trachtenberg system is a system of rapid mental calculation. The system consists of a number of readily memorized operations that allow one to perform arithmetic computations very quickly. It was developed by the Russian engineer Jakow Trachtenberg in order to keep his mind occupied while being in a Nazi concentration ...

   Your BMR can be calculated using direct calorimetry, indirect calorimetry, or a quick math equation. ... In particular, the Mifflin-St. Jeor equation is a popular way to calculate it quickly.

9. Approximations of π - Wikipedia

   en.wikipedia.org/wiki/Approximations_of_π

   The latter fraction is the best possible rational approximation of π using fewer than five decimal digits in the numerator and denominator. Zu Chongzhi's results surpass the accuracy reached in Hellenistic mathematics, and would remain without improvement for close to a millennium.
