A name server is a computer hardware or software server that implements a network service for providing responses to queries against a directory service.It translates an often humanly-meaningful, text-based identifier to a system-internal, often numeric identification or addressing component. name server indicates that its response is authoritative by setting the Authoritative Answer (AA) bit in the response to a query on a name for which it is authoritative. Name servers providing answers for which they are not authoritative (for example, name servers for parent zones) do not set the AA bit.
Trigonometry (from Greek trigÅnon, triangle and metron, measure) is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.
Graphs of Functions y = sin(x) and y = cos(x) Topic Index | Algebra2/Trig Index | Regents Exam Prep Center Graphs of trigonometric functions can be produced in degrees or in radians.The graphs appearing here will be done in radians.int: When hand-drawing the graphs of sine and cosine, draw vertical dotted lines at intervals to remind you of the connection to the quadrants from the unit circle and to keep your graphs accurate.
