Hyperbolic functions
The hyperbolic functions are the following:
hyperbolic sine:
(which is read as: shine x equals ...)
Hyperbolic sine y = sinh x
hyperbolic cosine:
(which is read as: cosh x equals ...)
Hyperbolic cosine y = cosh x
hyperbolic tangent:
(which is read as: tanch x equals ...)
Hyperbolic tangent y = tanh x
