COT

Syntax: COT (angle)
Location: QL ROM

This function returns the cotangent of a given angle (specified in radians).

COT(angle) can also be calculated as COS(angle)/SIN(angle).

NOTE:
COT(0) on most ROMs gives 1 - this  is fixed on Minerva, SMS, Lightning, QXL, and ST/QL which give an overflow error.

COT(PI/2) should equal zero - on all implementations of this command, this returns a number near to zero (except under SMS).

CROSS-REFERENCE:
Please refer to ACOT, ATAN, TAN.
Compare COTH.
