One approach is to delimit separate words with a non-alphanumeric character. The two characters commonly used for this purpose are the hyphen ("-") and the underscore ("_"); e.g., the two-word name "two words" would be represented as "two-words" or "two_words".
Another example of a delimiter is the time gap used to separate letters and words in the transmission of Morse code. [ citation needed ] In mathematics , delimiters are often used to specify the scope of an operation , and can occur both as isolated symbols (e.g., colon in " 1 : 4 {\displaystyle 1:4} ") and as a pair of opposing-looking symbols ...
When the variable appears in two sets of constraints, it is possible to substitute the new variables in the first constraints and in the second, and then join the two variables with a new "linking" constraint, [2] which requires that =
Separation of variables may be possible in some coordinate systems but not others, [2] and which coordinate systems allow for separation depends on the symmetry properties of the equation. [3] Below is an outline of an argument demonstrating the applicability of the method to certain linear equations, although the precise method may differ in ...
In casual use, the word "implies" loosely means suggests, rather than requires. However, in logic, the technical use of the word "implies" means "is a sufficient condition for." [3] That is the meaning intended by statisticians when they say causation is not certain.
Comma separated files are used for the interchange of database information between machines of two different architectures. The plain-text character of CSV files largely avoids incompatibilities such as byte-order and word size. The files are largely human-readable, so it is easier to deal with them in the absence of perfect documentation or ...
A variable may denote an unknown number that has to be determined; in which case, it is called an unknown; for example, in the quadratic equation ax 2 + bx + c = 0, the variables a, b, c are parameters, and x is the unknown. Sometimes the same symbol can be used to denote both a variable and a constant, that is a well defined mathematical object.
The Nastaʿlīq form of Islamic calligraphy uses vertical arrangement to separate words. The beginning of each word is written higher than the end of the preceding word, so that a line of text takes on a sawtooth appearance. Nastaliq spread from Persia and today is used for Persian, Uyghur, Pashto, and Urdu.
