A right triangle with sides relative to an angle at the point. Inverse trigonometric functions are useful when trying to determine the remaining two angles of a right triangle when the lengths of the sides of the triangle are known. Recalling the right-triangle definitions of sine and cosine, it follows that.

- Confusion with ¥ and Other Characters
As of November 2022[update], efforts to identify either the origin of this character or its purpose before the 1960s have not been successful. The earliest known reference found to date is a 1937 maintenance manual from the Teletype Corporation with a photograph showing the keyboard of its Kleinschmidt keyboard perforator WPE-3 using the Wheatstone...
Programming languages
In many programming languages such as C, Perl, PHP, Python, Unix scripting languages, and many file formats such as JSON, the backslash is used as an escape character, to indicate that the character following it should be treated specially (if it would otherwise be treated literally), or literally (if it would otherwise be treated specially). For instance, inside a C string literal the sequence \n produces a newline byte instead of an 'n', and the sequence produces an actual double quote r...
Filenames
MS-DOS 2.0, released 1983, copied the idea of a hierarchical file system from Unix and thus used the (forward) slash as the directory separator. Possibly on the insistence of IBM, Microsoft added the backslash to allow paths to be typed at the command line interpreter prompt, while retaining compatibility with MS-DOS 1.0 (in which / was the command-line option indicator. Typing "DIR/W" gave the "wide" option to the "DIR" command, so some other method was needed if one actually wanted to run a...
Text markup
The backslash is used in the TeX typesetting system and in RTFfiles to begin markup tags. In USFM, the backslash is used to mark format features for editing Bible translations. In caret notation, ^\ represents the control character 0x1C, file separator.This is entirely a coincidence and has nothing to do with its use in file paths.
In the Japanese encodings ISO 646-JP (a 7-bit code based on ASCII), JIS X 0201 (an 8-bit code), and Shift JIS (a multi-byte encoding which is 8-bit for ASCII), the code point 0x5C that would be used for backslash in ASCII is instead rendered as a yen sign ¥. Due to extensive use of the 005C code point to represent the yen sign, even today some font...
