Syntax
Cot(numAngle)
Cot ( numAngle )
numAngle
The angle in radians.
Tip: 2π radians is the same as 360 degrees.
Returned value
This function returns the cotangent of the specified angle.
The function cannot return the actual cotangent of π (that is, Cot(Pi()) or equivalent), because that is infinite. Instead, the function returns the largest number possible, given the limited precision of the value returned by the function Pi.
Examples
Calculate the cotangent of 1 radian:
Cot(1)
Calculate the cotangent of π/2 radians:
Cot(Pi()/2)
Calculate the cotangent of the value of the project tag MyAngle:
Cot(MyAngle)
