The hyperbolic functions are the trigonometric functions that are defined as the ratios of the sine and cosine of the hyperbolic angle. There are similarities between notations used for hyperbolic and trigonometric functions. Both trigonometric and hyperbolic functions have applications in many areas of engineering. For example, the shape of a chain hanging under gravity (known as a catenary curve) is described by the hyperbolic cosine, coshx, and the deformation of uniform beams can be expressed in terms of hyperbolic tangents. They are set of functions that take values greater than one, and are commonly used in physics, engineering and mathematics.
