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
Compliance
COT() is compatible with CT3’s COT().
