where the repeating block is indicated by dots over its first and last terms. [2] If the initial non-repeating block is not present – that is, if k = -1, a 0 = a m and = [;,, …, ¯], the regular continued fraction x is said to be purely periodic.
A repeating decimal or recurring decimal is a decimal representation of a number whose digits are eventually periodic (that is, after some place, the same sequence of digits is repeated forever); if this sequence consists only of zeros (that is if there is only a finite number of nonzero digits), the decimal is said to be terminating, and is not considered as repeating.
The model shows a steady increase of the mean solar day by 1.70 ms (±0.05 ms) per century, plus a periodic shift of about 4 ms amplitude and period of about 1,500 yr. [17] Over the last few centuries, rate of lengthening of the mean solar day has been about 1.4 ms per century, being the sum of the periodic component and the overall rate.
The table in the next section ("Ordered by yield") gives yields for notable radioactive (with half-lives greater than one year, plus iodine-131) fission products, and (the few most absorptive) neutron poison fission products, from thermal neutron fission of U-235 (typical of nuclear power reactors), computed from [permanent dead link ].
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...
The usual English proper name for Earth's natural satellite is simply Moon, with a capital M. [19] [20] The noun moon is derived from Old English mōna, which (like all its Germanic cognates) stems from Proto-Germanic *mēnōn, [21] which in turn comes from Proto-Indo-European *mēnsis 'month' [22] (from earlier *mēnōt, genitive *mēneses) which may be related to the verb 'measure' (of time).

The series stars Taylor Hickson as Raelle Collar, Jessica Sutton as Tally Craven, and Ashley Nicole Williams as Abigail Bellweather, three witches conscripted into the U.S. Army.
While the majority of plutinos have relatively low orbital inclinations, a significant fraction of these objects follow orbits similar to that of Pluto, with inclinations in the 10–25° range and eccentricities around 0.2–0.25; such orbits result in many of these objects having perihelia close to or even inside Neptune's orbit, while ...
