Definitions
General
The hyperbolic cosecant function is defined as:
The graph of the hyperbolic cosecant function is shown in the figure below.

Series
All hyperbolic functions can be defined in an infinite series form. Hyperbolic cosecant function can be written as:
The above series converges for . Bn denotes the n-th Bernulli number.
Properties
The derivative of the hyperbolic cosecant function is:
The integral of the hyperbolic cosecant is given by:
