Description

The Excel CSC function returns the cosecant of an angle provided in radians.

Formula syntax

CSC(array,number)

Arguments

  • number: required, the angle provided in radians, the absolute value of the number must be less than 2^27.

Returns

The CSC function returns a numeric value.

Errors

  • 2. If argument number is non-numeric, the CSC function returns #VALUE! error value.
  • 3. If argument number is zero, the CSC function returns #DIV/0! error value.

Remarks

  • 1. CSC(number) = 1/SIN(number)
  • 2. The argument number in CSC is an angle in radians, if the number is provided in degrees, you need to convert it to radians. There are two methods for converting degrees to radians. Method 1, multiply the angle in degrees by PI()/180. Method 2, used RADIANS function to convert degrees to radians. For example, to get the CSC of 30 degrees, you can use one of the formulas below:
    =CSC(30*PI()/180)
    =CSC(RADIANS(30))

Versions

Excel 2013 and later versions.

Usage and Examples

To get the cosecant of the angel provided in radians in cell B3, please use the formula as this:

=CSC(B3)

Press Enter key to get the cosecant of the angle.
