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/), và 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/), và 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") & so on.

Just as the points (cos t, sin t) size 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 kích cỡ 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 & elsewhere to lớn write the Sinhala language và also the liturgical languages Pali & Sanskrit. Being a thành viên of the Brahmic family of scripts, the Sinhalese script can trace its ancestry back more than 2,500 years.

Sinhalese is often considered two alphabets, or an alphabet within an alphabet, due to lớn the presence of two sets of letters. The vi xử lý core set, knoumakarahonpo.com 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 và Pali words, an extended set, the miśra siṃhala (mixed Sinhalese, මිශ්‍ර සිංහල), is available.

## Characteristics

The alphabet is written from left to right. The Sinhalese script is an abugida, 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 khổng lồ be written on dried palm leaves, which would split along the veins on writing straight lines. This was undesirable, và 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 and long double arguments. Those functions are identified by f and l suffixes respectively.
