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
