Real Quaternionic Calculus Handbook pp Cite as. The main focus of this chapter is to study the inverses of the quaternion trigonometric and hyperbolic functions, and their properties. Since the quaternion trigonometric and hyperbolic functions are defined in terms of the quaternion exponential function e p , it can be shown that their inverses are necessarily multi-valued and can be computed via the quaternion natural logarithm function ln p. The s facts we shall see here attest the great interest of these functions in mathematics.

hyperbolic function

In mathematics , hyperbolic functions are analogues of the ordinary trigonometric functions , but defined using the hyperbola rather than the circle. Just as the points cos t , sin t form a circle with a unit radius , the points cosh t , sinh t form the right half of the unit hyperbola. Hyperbolic functions occur in the calculations of angles and distances in hyperbolic geometry. They also occur in the solutions of many linear differential equations such as the equation defining a catenary , cubic equations , and Laplace's equation in Cartesian coordinates. Laplace's equations are important in many areas of physics , including electromagnetic theory , heat transfer , fluid dynamics , and special relativity.

The hyperbolic cosine and hyperbolic sine functions are:. We can easily create the other complex hyperbolic trigonometric functions. The derivatives of the hyperbolic functions are:. Some of the important identities involving the hyperbolic functions are:. There is a connection between complex hyperbolic and complex trigonometric functions:. Galileo's paradox.

In mathematics, hyperbolic functions are analogs of the ordinary trigonometric, or circular, functions. Just as the points cos t, sin t form a circle with a unit radius, the points cosh t, sinh t form the right half of the equilateral hyperbola. The hyperbolic functions take a real argument called a hyperbolic angle. The size of a hyperbolic angle is twice the area of its hyperbolic sector. The hyperbolic functions may be defined in terms of thelegs of a right triangle covering this sector. Hyperbolic functions occur in the solutions of many linear differential equations for example, the equation defining a catenary , of some cubic equations, in calculations of angles and distances in hyperbolic geometry, and of Laplace's equation in Cartesian coordinates. Laplace's equations are important in many areas of physics, including electromagnetic theory, heat transfer, fluid dynamics, and special relativity.

In these notes, we examine the inverse trigonometric and hyperbolic functions, where the arguments of these functions can be complex numbers. These are all multivalued functions. We also carefully define the corresponding single-valued principal values of the inverse trigonometric and hyperbolic functions following the conventions employed by the computer algebra software system, Mathematica.

Inverse Hyperbolic and Trigonometric Functions

Отсидев некоторое время в тюрьме, Хейл занялся поисками места программиста в частных компаниях. Он не скрывал от нанимателей того, что случилось с ним во время службы в морской пехоте, и стремился завоевать их расположение, предлагая работать без оплаты в течение месяца, чтобы они узнали ему цену. В желающих принять его на работу не было недостатка, а увидав, что он может творить на компьютере, они уже не хотели его отпускать.
