Hyperbolic function

In mathematics, hyperbolic functions are analogs of the ordinary trigonometric, or circular functions. The basic hyperbolic functions are the hyperbolic sine "sinh" (/ˈsɪntʃ/ or /ˈʃaɪn/), and the hyperbolic cosine "cosh" (/ˈkɒʃ/), from which are derived the hyperbolic tangent "tanh" (/ˈtæntʃ/ or /ˈθæn/),hyperbolic cosecant "csch" or "cosech" (/ˈkoʊʃɛk/ or /ˈkoʊsɛtʃ/), hyperbolic secant "sech" (/ˈʃɛk/ or /ˈsɛtʃ/), and hyperbolic cotangent "coth" (/ˈkoʊθ/ or /ˈkɒθ/), corresponding to the derived trigonometric functions. The inverse hyperbolic functions are the area hyperbolic sine "arsinh" (also called "asinh" or sometimes "arcsinh") and so on.

Just as the points (cos t, sin t) form a circle with a unit radius, the points (cosh t, sinh t) form the right half of the equilateral hyperbola. The hyperbolic functions take a real argument called a hyperbolic angle. The size of a hyperbolic angle is twice the area of its hyperbolic sector. The hyperbolic functions may be defined in terms of the legs of a right triangle covering this sector.

¡Que viva México!

¡Que viva México! (Russian: Да здравствует Мексика!) is a film project begun in 1930 by the Russian avant-garde director Sergei Eisenstein (1898–1948). It would have been an episodic portrayal of Mexican culture and politics from pre-Conquest civilization to the Mexican revolution. Production was beset by difficulties and was eventually abandoned. Jay Leyda and Zina Voynow call it his "greatest film plan and his greatest personal tragedy".

Overview

Eisenstein left for Mexico in December 1930—after various projects proposed by Charles Chaplin and Paramount Pictures fell through, and Paramount released him from his contract. The Mexican film was produced by Upton Sinclair and a small group of financiers recruited by his wife Mary Craig Kimbrough Sinclair, under a legal corporation these investors formed, the Mexican Film Trust. Their contract with Eisenstein called for a short, apolitical feature film about or involving Mexico, in a scenario to be designed and filmed by Eisenstein and his two compatriots, Grigori Alexandrov and Eduard Tisse. Other provisos of the contract, which Eisenstein signed on 24 November 1930, included that the film would be completed (including all post-production work) by April 1931, and would show or imply nothing that could be construed as insulting to or critical of post-Revolution Mexico (a condition imposed by the Mexican government before it would allow the three Soviets entry into their country). Filmed material was also to be subject to censorship by the Mexican government, at first after it was filmed and printed, later in 1931 during shooting via an on-site censor.

Đàm Vĩnh Hưng (born October 2, 1971), often referred to by his nickname, Mr. Dam (also spelled Mr. Đàm), is a Vietnamese pop star.

He has become very popular in Vietnam beginning with his first career solo “Tình Ơi Xin Ngủ Yên”. His second album, "Binh Minh Se Mang Em Di," boosted him into the A-list singers in Vietnam receiving much commercial and critical success. Following that, his first official liveshow "Trai Tim Hat" was held in 2013, directed by the most famous director at that time, Huynh Phuc Dien. The success of his albums as well as his live concerts had led him into many awards; he was named one of top 10 singers of the year by Lan Song Xanh from that on and especially the award of "Best Male Artist of the year" of Ngoi Sao Bach Kim was given as a proof of his effort.

However, his career life was truly brightened when his 5th album-Giot Nuoc Mat Cho Doi was given out, followed by his second liveshow "Gio H". On the other hand, Vol 8 "Tinh Ca 50" releasing in 2006 briging him a lot of troubles from the song of the same name. There was also a rumour of the love affair between Hung and one of the very famous Vietnamese female singer - My Tam at that time when Hung continuously confessed about his admiration for Tam.
