secanth, cosecanth, cotangenth

The three reciprocal hyperbolic trigonometric functions are:

sech(x) - secanth
csch(x) - cosecanth
coth(x) - cotangenth

sech(x) = 1/cosh(x)
csch(x) = 1/sinh(x)
coth(x) = 1/tanh(x)

Each one of these functions works in radians and can accept real and complex numbers.
Each one of these functions has an inverse, reciprocal, and non-hyperbolic version.
