This article describes the formula syntax and usage of the CSC function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.
Returns the cosecant of an angle specified in radians.
The CSC function syntax has the following arguments.
- The absolute value of Number must be less than 2^27.
- If Number is outside its constraints, CSC returns the #NUM! error value.
- If Number is a non-numeric value, CSC returns the #VALUE! error value.
- CSC(n) equals 1/SIN(n).
The workbook below shows examples of this function. Inspect them, change existing formulas, or enter your own formulas to learn how the function works.
To work more in-depth with the example data in Excel, download the embedded workbook to your computer, and then open it in Excel.
