The CSC function returns the cosecant of a number given in radians.
This function takes a single as input. It parses that Number in radians and outputs its cosecant.
number(required, type: Number) The number to calculate the cosecant of. This number is parsed in radians.
cosecant(type: Number) The cosecant of the given number.
The following example returns the cosecant of 45. Note that while the secant of 45 degrees is √2, the tangent of 45 radians is 1.175221363135749 and this is the number the CSC function returns:
In order to calculate the cosecant of a number of degrees, said number must first be converted into radians using the function . The following example returns the cosecant of forty-five degrees by first converting forty-five degrees into radians and then calculating the cosecant of the resulting number. Note that the output is a numerical estimation of √2:
Mathematically, the cosecant of 0 radians is undefined, and so when 0 is given as input for the SEC function, it outputs NULL, such as in the following example:
Mathematically, the cosecant of an angle is the reciprocal of the sine of that angle. The relationship between the functions CSC and is the same, such that, for some number n:
