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 the trigonometric functions. Zeros of a function. The graph of y = sin x. The period of a function. The graph of y = cos x. The graph of y = sin ax. The graph of y = tan x. L ET US BEGIN by introducing some algebraic language.ere is the graph of y = sin x : The height of the curve at every point is the line value of the sine. In the language of functions, y = sin x is an odd function.
