Trigonometry (2,568 Books)


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.
