Description of COT Function

  • It is one of the built-in functions in Microsoft Excel.
  • This function returns the cotangent values (ratio) of the given (angle) radians.
  • To convert the degree value into radians, use RADIANS(number) function.
  • For example, RADIANS(0.52) returns the secant value as 1.732.

Syntax

  • Here, you will see the syntax of the COT function.
  • To apply this function on your spreadsheet, you have to select a cell and enter the formula in the following format.
  • Once you enter the formula, just click on the Enter button to get the result.

Argument Explanation

Number – The angle in radians to which you need to find the cotangent value.

Note: If the argument is a non-numeric value (letters and special characters) and then it returns #VALUE! Error.

Examples

Here, we come up with some examples to know how to use the COT function in the Excel spreadsheet.

  • Initially, you have to open your Excel workbook on your PC and launch a worksheet that has data.
  • For example, we have given the degree values in Column B, and their corresponding radians in Column C.
  • Here, we will get the cotangent value of the given radians in Column E using the COT function.
