COT()

Cotangent of the argument

Syntax

COT (nRadiant) -> nCotangent

Arguments

<nRadiant> an angle size given in radiants

Returns

<nCotangent> the cotangent of <nRadiant>

Description

The function COT() calculates the cotangent of an angle whose size is given in radiants (full angle equals 2*Pi - see DTOR() for angle size given in degress). A common geometric interpretation of the COT() function is the ankathede-counterkathede-ratio of a right-angled triangle, or, cot(x) = cos(x)/sin(x)=1/tan(x).
Examples
      ? cot (1.0) --> 0.6420...
Tests
      cot (PI()/4) == 1
      cot (PI()/2) == 0
