The hyperbolic functions appear with some frequency in applications, and are quite similar in many respects to the trigonometric functions. This is a bit surprising given our initial definitions. Definition 4. Graphs are shown in figure 4. Certainly the hyperbolic functions do not closely resemble the trigonometric functions graphically. But they do have analogous properties, beginning with the following identity. Theorem 4.
The hyperbolic functions have identities that are similar to those of trigonometric functions:. In certain cases, the integrals of hyperbolic functions can be evaluated using the substitution. The hyperbolic cosine is a positive function. Hence, we can write the answer in the form. Necessary cookies are absolutely essential for the website to function properly.

Calculating the series expansion of hyperbolic functions to hundreds of terms can be done in seconds. Here are some examples. After loading this package, and using the package function SeriesTerm , the following term for odd hyperbolic functions can be evaluated. This series should be evaluated to , which can be concluded from the following relation. Mathematica can evaluate derivatives of hyperbolic functions of an arbitrary positive integer order. Mathematica can calculate finite sums that contain hyperbolic functions. Here are two examples.
We were introduced to hyperbolic functions in Introduction to Functions and Graphs , along with some of their basic properties. In this section, we look at differentiation and integration formulas for the hyperbolic functions and their inverses. The other hyperbolic functions are then defined in terms of sinh x sinh x and cosh x. The graphs of the hyperbolic functions are shown in the following figure. It is easy to develop differentiation formulas for the hyperbolic functions.
We were introduced to hyperbolic functions previously, along with some of their basic properties. In this section, we look at differentiation and integration formulas for the hyperbolic functions and their inverses. It is easy to develop differentiation formulas for the hyperbolic functions. There are a lot of similarities, but differences as well. For example, the derivatives of the sine functions match:.
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 functions are functions that have many applications to mathematics, physics, and engineering. Among many other applications, they are used to describe the formation of satellite rings around planets, to describe the shape of a rope hanging from two points, and have application to the theory of special relativity. This section defines the hyperbolic functions and describes many of their properties, especially their usefulness to calculus. The following example explores some of the properties of these functions that bear remarkable resemblance to the properties of their trigonometric counterparts. The following Key Idea summarizes many of the important identities relating to hyperbolic functions.
