COT
Formulas / COTTo calculate the cotangent of a specified angle in radians, which is the reciprocal of the tangent of the angle.
=COT(number)
- number - The angle in radians for which the cotangent is to be calculated.
Examples
=COT(PI()/4)This formula calculates the cotangent of π/4 radians (45 degrees) and returns the result, which is approximately 1.
=COT(0)This formula calculates the cotangent of 0 radians (0 degrees) and returns the result, which is an error (#DIV/0!) because the cotangent of 0 radians is undefined.

Summary
The COT function calculates the cotangent of a given angle in radians.
- The COT function calculates the cotangent of a given angle in radians, which is the reciprocal of the tangent of the angle.
- The COT function returns a #DIV/0! error if the argument corresponds to an angle where the tangent is zero (e.g., π/2, 3π/2).
- The COT function expects the angle to be provided in radians; if the angle is given in degrees, it must be converted to radians using the RADIANS function.
Frequently Asked Questions
What does the COT function do?
The COT function calculates the cotangent of a given angle in radians and returns the result. The cotangent is the reciprocal of the tangent of the angle.
What error does COT return if the angle is a multiple of π (180 degrees)?
COT returns a #DIV/0! error if the angle is a multiple of π (180 degrees) because the cotangent of such angles is undefined.
Can COT be used with other trigonometric functions?
Yes, COT can be used with other trigonometric functions such as SIN, COS, and TAN to perform various trigonometric calculations.
What is the input unit for the angle in the COT function?
The input unit for the angle in the COT function is radians. If the angle is given in degrees, it should be converted to radians before using it in the COT function.
