sinh (= hyperbolic sin) is just one of the hyperbolic functions, each represents an open-ended curve on an x-y plot. Besides being open-ended, the function also has to meet other criteria to be hyperbolic -- it can be formed with the intercept between a plane and a cone, for example.
Specifically, sinh x = (ex - e-x)/2. I got the following values from Microsoft Excel:
x sinh(x)
-10 -11013.23287

If you plot the columnar data in Excel, you will see the curve will go +infinity to the right of the y-axis and -infinity to the left (hence, open-ended), and has an odd symmetry (y(-x) = -y(x)).
An arc-hyperbolic function is an inverse hyperbolic function.
∫ cosh(x) dx = sinh(x) + C C is the constant of integration.
Yes, but it is called a hyberbolic trigonometric function
The hyperbolic functions are related to a hyperbola is the same way the the circular functions are related to a circle. So, while the points with coordinates [cos(t), sin(t)] generate the unit circle, their hyperbolic counterparts, [cosh(t) , sinh(t)] generate the right half of the equilateral hyperbola. Other circular functions (tan, sec, cosec and cot) also have their hyperbolic counterparts, as do the inverse functions. An alternative, equivalent pair of definitions is: cosh(x) = (ex + e-x)/2 and sinh(x) = (ex - e-x)/2
∫ 1/sinh(x) dx = ln(tanh(x/2)) + C C is the constant of integration.
sinh(x) = ½[ex-e-x]
The equation of a hyperbolic function is y = sinh(x) or y = cosh(x), where sinh(x) represents the hyperbolic sine function and cosh(x) represents the hyperbolic cosine function. Hyperbolic functions are similar to trigonometric functions but are defined in terms of exponentials.
An arc-hyperbolic function is an inverse hyperbolic function.
It is used in hyperbolic functions; it's the rule to change a normal trig function into hyperbolic trig function. Example: cos(x-y) = cosx cosy + sinx siny Cosh(x-y) = coshx coshy - sinhx sinhy Whenever you have a multiplication of sin, you write the hyperbolic version as sinh but change the sign. also applied when: tanxsinx (sinx)^2 etc... Hope this helps you
It is a hyperbolic function.
