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
