Synopsis

(std-sinh <radians>) ; hyperbolic sine

(std-cosh <radians>) ; hyperbolic cosine

(std-tanh <radians>) ; hyperbolic tangent

(std-coth <radians>) ; hyperbolic cotangent

(std-sech <radians>) ; hyperbolic secant

(std-csch <radians>) ; hyperbolic cosecant

(std-arsinh <real>) ; hyperbolic area sine

(std-arcosh <real>) ; hyperbolic area cosine

(std-artanh <real>) ; hyperbolic area tangent

(std-arcoth <real>) ; hyperbolic area cotangent
