CSC Trigonometric Cosecant Function

Section: Mathematical Functions

# Usage

Computes the `csc` function for its argument. The general syntax for its use is

      y = csc(x)

where `x` is an `n`-dimensional array of numerical type. Integer types are promoted to the `double` type prior to calculation of the `csc` function. Output `y` is of the same size and type as the input `x`, (unless `x` is an integer, in which case `y` is a `double` type).

# Internals

Mathematically, the `csc` function is defined for all arguments as

# Example

The following piece of code plots the real-valued `csc(2 pi x)` function over the interval of `[-1,1]`:

    --> t = linspace(-1,1,1000);
    --> plot(t,csc(2*pi*t))
    --> axis([-1,1,-10,10]);
