Real world uses of hyperbolic trigonometric functions
2017年1月27日 · Most curves that look parabolic are actually Catenaries, which is based in the hyperbolic cosine function. A good example of a Catenary would be the Gateway Arch in Saint Louis, Missouri. The tractrix, which is based in the hyperbolic secant, is also known as the pursuit curve, which models objects like cargo trucks turning corners, or a dog on ...

Hyperbolic or exponential solutions to differential equation
2015年12月6日 · There are several examples that I'd love to present to show why expressing your solutions as a sum of hyperbolic trig functions. There are properties of hyperbolic trig functions that are so closely related to the familiar circular trig functions that manipulating them can be very natural (as opposed to working with a sum of 2 exponentials).
Unifying the connections between the trigonometric and …
2021年1月25日 · Sine and hyperbolic sine are odd, whereas cosine and hyperbolic cosine are even. But sine and cosine are periodic functions, unlike the hyperbolic counterparts. The analogue of the identity $\cos^2x+\sin^2x \equiv 1$ is $\cosh^2x-\sinh^2x \equiv 1$ .
How were hyperbolic functions derived/discovered?
2018年4月18日 · $\begingroup$ The hyperbolic cosine arises naturally in physics when looking at suspended chains of uniform mass. $\endgroup$ – Pedro ♦ Commented Jul 30, 2013 at 14:37
Relationship between hyperbolic functions and complex analysis
2018年8月30日 · For example, the hyperbolic cosine: $$\cosh x = \frac{e^x + e^{-x}}{2}$$ There is a result in complex analysis that looks uncannily Skip to main content Stack Exchange Network
The interconnection between Hyperbolic functions and Euler's …
2018年7月16日 · It is called sinh because it is the hyperbolic equivalent of sine. It is called cosh because it is the hyperbolic equivalent of cosine. There is an interesting function, called the Gudermannian function that ties the circular and the hyperbolic functions together without using complex numbers.
geometry - Geometric meanings of hyperbolic cosine and sine ...
2014年3月20日 · For the hyperbolic plane, the story is similar, the area of a triangle is proportional to the “hyperbolic defect”, namely $\pi$ minus the sum of the angles. In particular, the area of a triangle whose three vertices are “out at infinity”, with angles of zero, should be $\pi$.
Intuition Behind the Hyperbolic Sine and Hyperbolic Cosine …
There is an absolutely fascinating little booklet called "Hyperbolic Functions" by V. G. Shervatov in which the author develops circular and hyperbolic functions in parallel from a purely geometric viewpoint.
Range of Real Inverse Hyperbolic Cosine -- can it be negative?
2021年1月2日 · Technically speaking, the hyperbolic cosine is not an invertible function, and the notation $\cosh^{-1}(x)$ is no so valid. The function $\text{arcosh}(x)$ is well-known and "by default" taken to be the principal branch.
