COT(angle)
angle
The angle in radians for which you want the cotangent. For example: PI()/4, 1.5, RADIANS(45), A1.
More details
COT calculates the cotangent of an angle in radians. Cotangent equals 1/TAN(angle) or COS(angle)/SIN(angle). Returns #DIV/0! error when the sine of the angle is zero (multiples of π). Use RADIANS() to convert degrees to radians if needed.
