• trigonométrie - mathématiques.

  On montre facilement que ces quatre fonctions trigonométriques ne dépendent que de l’angle θ et non directement du choix du point P. On peut remarquer que ces fonctions trigonométriques sont périodiques, c’est-à-dire qu’elles reprennent les mêmes valeurs à intervalles réguliers appelés périodes. Les fonctions cosinus et sinus sont périodiques de périodes 2 p, c’est-à-dire que, pour tout entier relatif k (voir Nombres), cos ( θ + 2 kp) = cos θ et sin ( θ + 2 kp) = sin θ. Quant aux fonctions...

• norvégienne, littérature.

  vie rurale et les traditions est au centre des romans et poèmes d'Arne Garborg. Les années 1890 furent marquées par l'éclosion du mouvement néoromantique. La poésie lyrique fut remise au goût du jour et trouve ses plus belles illustrations dans les œuvres de Nils Collett Vogt, Vilhelm Krag et, tout particulièrement, Sigbjørn Obstfelder. L'individualisme artistique et la satire sont à l'honneur dans les pièces de Gunnar Heiberg. Dans ses contes et romans, Hans Kinck souligne l'interaction qui exi...

  artists in the Ohio area cut delicate flat forms from sheets of mica in the shape of birds, human figures, and large hands. They also carved quite natural-looking birdsand animals on stone platform pipes. These figures sat on the pipe’s flat base, or platform, and on some pipes they were part of the pipe bowl.

  La désintégration radioactive peut prendre différentes formes : désintégration alpha, bêta, par capture d'électron. Ces différents modes de désintégration s'accompagnentparfois de l'émission d'ondes électromagnétiques (X ou gamma) de grande énergie ( voir radioactivité). Les scientifiques caractérisent la radioactivité d'un élément par son temps de demi-vie, ou période radioactive. C'est le temps au terme duquel la moitié des nucléides del'élément se sont désintégrés. Par exemple, la période r...

Such notes disclose information that is not already included inthe body of the financial statement.

The notes also disclose information about lease commitments, contingent liab...

Often theelders of a town constituted a tribunal. The judges could not reverse their decisions for any reason, but appeals from their...

Observations from telescopes on Earth and in space indicate that most of the gases in the coma and tail of a comet are fragmentary molecules, or radicals, of the mostcommon elements in space: hydrogen, carbon, nitrogen, and oxygen. The radicals, for example, of CH, NH, and OH may be broken away from the stable molecules CH 4 (methane), NH 3 (ammonia), and H 2O (water), which may exist as ices or more complex, very cold compounds in the nucleus.

The parent pieces of rock from which chips have beendetached are called cores, and the chips that have been removed from cores are called flakes. A flake that has had yet smaller flakes removed from one or more edgesin orde...

• Rembrandt.

  myth that the painting was rejected by those who commissioned it, and led to a decline in Rembrandt's reputation and fortune, it was actually well received. Many of Rembrandt's landscapes in this middle period are romantic and based on his imagination rather than recording specific places. The inclusion of ancient ruins androlling hills, not a part of the flat Dutch countryside, as in River Valley with Ruins (Staatliche Gemäldegalerie, Kassel), suggests a classical influence derived from Italy...

• Archaeology.

  Prehistoric archaeology is practiced by archaeologists known as prehistorians and deals with ancient cultures that did not have writing of any kind. Prehistory, a term coined by 19th-century French scholars, covers past human life from its origins up to the advent of written records. History—that is, the human past documented insome form of writing—began 5000 years ago in parts of southwestern Asia and as recently as the late 19th century AD in central Africa and parts of the Americas.

• Human Sexuality.

  About six weeks after conception, if a Y chromosome is present in the embryo's cells (as it is in normal males), a gene on the chromosome directs the undifferentiatedgonads to become testes. If the Y chromosome is not present (as in normal females), the undifferentiated gonads will become ovaries. If the gonads become testes, they begin to produce androgens (male hormones, primarily testosterone) by about eight weeks after conception. These androgens stimulate development of the one set of the...

  However, these reforms faced serious opposition. The feudal barons formed an alliance and rebelled against Wang Mang.

  Swept up in the hype, the Rangers came out for game five at the Garden in a virtual sleepwalk. By the start of the third period they were down 3-0. New Yorkscratched back to level the score as Messier culminated the three-goal spurt with a wrist shot midway through the period. Vancouver then stunned the Rangers—andthe sellout crowd—by netting three quick goals to put the game far out of reach. Game six in Vancouver proved even more of a challenge for the Rangers. The team showed little will...

Les Mémoires d’un âne rapporte à lui seul plus de trois millions or, et la comtesse de Ségur doit écrire deux romans par an jusqu’en 1871 ( les Petites Filles modèles, 1859 ; les Malheurs de Sophie, la Fortune de Gaspard, 1864 ; Un bon petit diable, 1865 ; le Général Dourakine, 1866), tous illustrés par de grands artistes, parmi lesquels figure Gustave Doré. Sans doute ce succès s’explique-t-il d’abord par la nature des intrigues qui composent ces ouvrages. Malgré leur mièvreri...

• L e terme de crise économique désigne une rupture dans l'activité d'un pays ou d'un ensemble de pays ; on le réserve donc à un phénomène macro-économique, par opposition aux crises sectorielles ou locales, qui n'affectent qu'une partie de l'économie.

  Les crises cycliques Dans les pays industrialisés, la disparition des crises d'origine frumentaire n'a pas signifié celle de toute crise économique. Au contraire, on a observé avant la Première Guerre mondiale une alternance régulière de périodes d'expansion et de récession – la crise étant le passage brutal de l'une à l'autre –, comme en 1836, 1847, 1857, 1866, 1873, 1882, 1893, 1907, 1913 ( voir cycle économique ). Deux aspects la caractérisent : elle est endogène, en ce que les fluctuations...
