The CSC function returns the cosecant of an angle specified in radians.
- This function was introduced in Excel 2013 and so is not available in earlier versions.
|number||The angle, in radians, for which you want the cosecant
|2||=CSC(15)||1.538||Returns the cosecant of 15|
|3||=CSC(-6)||3.578899547||Returns the cosecant of -6|
|4||=CSC(RADIANS(45))||1.414213562||Returns the cosecant of 45 degree angle|
Note: If the angle is in degrees, you need to be convert it to radians before supplying it to the CSC function. You can convert it, using the RADIANS function: =RADIANS(degrees)
Common Function Error(s)
|Problem||What went wrong|
|#VALUE!||Occurs if the supplied number argument is not recognized as a numeric value|
|#NUM!||Occurs if the supplied number argument is less than -2^27 or is greater than 2^27|
|#DIV/0!||Occurs if the supplied number argument is equal to zero|
The cosecant is the reciprocal of sine. For the simple right-angle triangle at right, the cosecant of angle A is equal to the hypotenuse (h), divided by the opposite side (a). The formula for calculating cosecant is:
