# CSC function

## Description

Cosecant function. CSC(x) returns the cosecant of x. The argument x must be expressed in radians. To convert degrees to radians you use the RADIANS function.

The cosecant is the reciprocal of the sine:

$$ \operatorname{csc}(x) = \frac{1}{\operatorname{sin}(x)} $$

The argument x can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the CSC function applied to all elements.
