In mathematics, Euler's identity[note 1] (also known as Euler's equation) is the equality where. is pi, the ratio of the circumference of a circle to its diameter. Euler's identity is named after the Swiss mathematician Leonhard Euler. It is a special case of Euler's formula when evaluated for .
Euler's formula provides a means of conversion between cartesian coordinates and polar coordinates. The polar form simplifies the mathematics when used in multiplication or powers of complex numbers. Any complex number z = x + iy, and its complex conjugate, z = x − iy, can be written as where. φ = arg z = atan2 (y, x).
The Czechoslovak koruna (in Czech and Slovak: koruna československá, at times koruna česko-slovenská; koruna means crown) was the currency of Czechoslovakia from 10 April 1919 to 14 March 1939, and from 1 November 1945 to 7 February 1993. For a brief time in 1939 and again in 1993, it was also the currency of both the separate Czech ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property ...
Spaces within a formula must be directly managed (for example by including explicit hair or thin spaces). Variable names must be italicized explicitly, and superscripts and subscripts must use an explicit tag or template. Except for short formulas, the source of a formula typically has more markup overhead and can be difficult to read.
The koruna, or crown (sign: Kč; code: CZK, Czech: koruna česká), has been the currency of the Czech Republic since 1993. The koruna is one of the European Union 's eight currencies, and the Czech Republic is legally bound to adopt the euro in the future. The official name in Czech is koruna česká (plural koruny české, though the zero ...
t. e. The Czech Republic is bound to adopt the euro in the future and to join the eurozone once it has satisfied the euro convergence criteria by the Treaty of Accession since it joined the European Union (EU) in 2004. The Czech Republic is therefore a candidate for the enlargement of the eurozone and it uses the Czech koruna as its currency ...
In chemistry, a formula unit is the smallest unit of a non-molecular substance, such as an ionic compound, covalent network solid, or metal. [1][2] It can also refer to the chemical formula for that unit. Those structures do not consist of discrete molecules, and so for them, the term formula unit is used. In contrast, the terms molecule or ...
