  2. Continued fraction - Wikipedia

    en.wikipedia.org/wiki/Continued_fraction

    A continued fraction is an expression of the form = + + + + + where the a n (n > 0) are the partial numerators, the b n are the partial denominators, and the leading term b 0 is called the integer part of the continued fraction.

  3. Periodic continued fraction - Wikipedia

    en.wikipedia.org/wiki/Periodic_continued_fraction

    By considering the complete quotients of periodic continued fractions, Euler was able to prove that if x is a regular periodic continued fraction, then x is a quadratic irrational number. The proof is straightforward. From the fraction itself, one can construct the quadratic equation with integral coefficients that x must satisfy.

    By column chromatography on regular silica gel with a hexane / ethyl acetate eluent (5:1), a 66.6% ee sample of a trifluoromethyl substrate is separated into several fractions ranging from 8.1% ee for the first fraction collected to > 99.9% ee for the last fraction collected.

  6. Arctic Circle - Wikipedia

    en.wikipedia.org/wiki/Arctic_Circle

    The Arctic Circle, roughly 67° north of the Equator, defines the boundary of the Arctic waters and lands. The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth at about 66° 34' N. [1] Its southern equivalent is the Antarctic Circle.

    The meridian 66° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, North America, the Atlantic Ocean, the Caribbean Sea, South America, the Southern Ocean, and Antarctica to the South Pole.

  8. Six-bit character code - Wikipedia

    en.wikipedia.org/wiki/Six-bit_character_code

    A six-bit character code is a character encoding designed for use on computers with word lengths a multiple of 6. Six bits can only encode 64 distinct characters, so these codes generally include only the upper-case letters, the numerals, some punctuation characters, and sometimes control characters.

  9. Usage share of operating systems - Wikipedia

    en.wikipedia.org/wiki/Usage_share_of_operating...

    Currently, 3.1 billion smartphones and tablets are in use across the world (with tablets, a small fraction of the total, generally running the same operating systems, Android or iOS, the latter being more popular on tablets. In 2019, a variant of iOS called iPadOS built for iPad tablets was released).
