Trigonometry (from Greek trigonon 'triangle' + metron 'measure' or from Sanskrit trikon 'triangle' + miti 'measurement' = trikonmiti) is a branch of mathematics that studies triangles and the relationships between their sides and the angles between the sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies.

Introduction: Directory Services are a fundamental requirement of both human and computer communications' systems. Human users need to be able to look up various details about other people: for example, telephone numbers, facsimile numbers and paper mail addresses. Computing systems also need Directory Services for several purposes: for example, to support address look-ups for a variety of services, and to support user-friendly naming and distribution lists in electronic mail systems.
Excerpt: The set you suggest was created, I assume, by the systems programmer(s) who wrote TELNET in TENEX. It is a set of historical accidents, and shows it. A better source for standard mnemonics might be the NIC site codes, since these have been chosen with more care and will become familiar as we begin to use the NIC on-line. Surely the NIC is a more reasonable source for a defacto standard than a particular system programmer.
Introduction: With the growing internationalization of the Internet, support for many coded character sets is required. It is the intention of this memo to document precisely the mapping between all characters and their corresponding coded representations in various coded character sets, and give names to these coded character sets, so they can be referenced unambiguously in Internet standards.
