The CSC function employs the following syntax to operate:
CSC(number)
The CSC function has the following arguments:
- number: this is required.
It should be further noted that:
- 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).
Please see my example below:
