Hanoi (/hæˈnɔɪ/ or US /həˈnɔɪ/; Vietnamese: Hà Nội Thủ Đô ) is the capital of Vietphái nam and the country"s second largest đô thị. Its population in 2009 was estimated at 2.6 million for urban districts và 7 million for the metropolitan jurisdiction. The number of population in năm ngoái was estimated at 7.7 million people. From 1010 until 1802, it was the most important political centre of Vietnam. It was eclipsed by Huế, the imperial capital of Vietphái mạnh during the Nguyễn Dynasty (1802–1945), but Hanoi served as the capital of French Indochina from 1902 lớn 1954. From 1954 to lớn 1976, it was the capital of North Vietphái mạnh, và it became the capital of a reunified Vietnam in 1976, after the North"s victory in the Vietphái mạnh War.

The thành phố lies on the right ngân hàng of the Red River. Hanoi is 1,760 km (1,090 mi) north of Ho Chi Minch City and 120 km (75 mi) west of Hai Phong đô thị.

October 2010 officially marked 1000 years since the establishment of the thành phố. The Hanoi Ceramic Mosaic Mural is a 4 km ceramic mosaic mural created to lớn mark the occasion.

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/), & 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/), & hyperbolic cotangent "coth" (/ˈkoʊθ/ or /ˈkɒθ/), corresponding to lớn the derived trigonometric functions. The inverse hyperbolic functions are the area hyperbolic sine "arsinh" (also called "asinh" or sometimes "arcsinh") và so on.

Just as the points (cos t, sin t) size a circle with a unit radius, the points (cosh t, sinh t) khung the right half of the equilateral hyperbola. The hyperbolic functions take a real argument called a hyperbolic angle. The form 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.

Sinhala alphabet

The Sinhalese alphabet (Sinhala:සිංහල අක්ෂර මාලාව) (Sinhala Akṣara Malava) is an abugida used by the Sinhala people in Sri Lanka và elsewhere lớn write the Sinhala language & also the liturgical languages Pali and Sanskrit. Being a member of the Brahmic family of scripts, the Sinhalese script can trace its ancestry baông xã more than 2,500 years.

Sinhalese is often considered two alphabets, or an alphabet within an alphabet, due lớn the presence of two sets of letters. The core mix, as the śuddha siṃhala (pure Sinhalese, ශුද්ධ සිංහල) or eḷu hōḍiya (Eḷu alphabet එළු හෝඩිය ), can represent all native phonemes. In order lớn render Sanskrit & Pali words, an extended mix, the miśra siṃhala (mixed Sinhalese, මිශ්‍ර සිංහල), is available.


The alphabet is written from left khổng lồ right. The Sinhalese script is an abugidomain authority, as each consonant has an inherent vowel (/a/), which can be changed with the different vowel signs or removed (see image on left for examples).

Most of the Sinhalese letters are curlicues; straight lines are almost completely absent from the alphabet. This is because Sinhala used to lớn be written on dried palm leaves, which would split along the veins on writing straight lines. This was undesirable, and therefore, the round shapes were preferred.

C mathematical functions

C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. All functions use floating point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions. Most of these functions are also available in the C++ standard library, though in different headers (the C headers are included as well, but only as a deprecated compatibility feature).

Overview of functions

Most of the mathematical functions are defined in math.h (cmath header in C++). The functions that operate on integers, such as abs, labs, div, & ldiv, are instead defined in the stdlib.h header (cstdlib header in C++).

Any functions that operate on angles use radians as the unit of angle.

Not all of these functions are available in the C89 version of the standard. For those that are, the functions accept only type double for the floating-point arguments, leading lớn expensive type conversions in code that otherwise used single-precision float values. In C99, this shortcoming was fixed by introducing new sets of functions that work on float và long double arguments. Those functions are identified by f and l suffixes respectively.

Clip or CLIP may refer to:


Binder clip, a device used for holding thicker materials (such as large volumes of paper) together
đoạn Clip (firearms)

A clip is a device that is used to store multiple rounds of ammunition together as a unit, ready for insertion into the magazine or cylinder of a firearm. This speeds up the process of loading và reloading the firearm as several rounds can be loaded at once, rather than one round being loaded at a time. Several different types of clips exist, most of which are made of inexpensive metal stampings that are designed khổng lồ be disposable, though they are often re-used.

The defining difference between clips và magazines is the presence of a feed mechanism in a magazine, typically a spring-loaded follower, which a clip lacks.

A stripper clip or charger is a speed-loader that holds several cartridges together in a single unit for easier loading of a firearm"s magazine. A stripper clip is used only for loading the magazine and is not necessary for the firearm to lớn function. It is called a "stripper" clip because, after the bolt is opened and the stripper clip is placed in position (generally by placing it in a slot on either the receiver or bolt), the cartridges are pressed, thereby "stripping" them off the stripper clip and into the magazine.
