From this page, https://en.wikipedia.org/wiki/Inverse_hyperbolic_functions, I see that ##\sinh(\cosh^{-1}(x) = \sqrt{x^2 - 1}##, for |x| > 1.Clara Chung said:
Thank you. I get the answer.Mark44 said:

Hyperbolic functions are mathematical functions that are closely related to trigonometric functions. They are defined in terms of the hyperbola, which is a type of geometric curve. Some common hyperbolic functions include the hyperbolic sine, cosine, and tangent.
Hyperbolic functions are used in many areas of science, particularly in physics and engineering. They are used to model various physical phenomena, such as the shape of a hanging chain or the trajectory of a projectile. They are also used in signal processing, control theory, and other areas of mathematics.
Hyperbolic functions have many properties that are similar to trigonometric functions. For example, they have specific ranges and domains, and they exhibit periodic behavior. They also have inverse functions, which can be used to solve equations involving hyperbolic functions.
Solving hyperbolic function problems involves using algebraic techniques and knowledge of the properties of hyperbolic functions. This may include simplifying expressions, using trigonometric identities, or using the properties of inverse functions. It is also important to carefully define the domain and range of the functions being used.
Hyperbolic functions have many practical applications in various fields. In physics, they are used to model the motion of objects under the influence of gravity. In economics, they are used to model growth and decay rates. In engineering, they are used to design structures such as bridges and arches. They are also used in statistics, biology, and other fields.
