Sech hyperbolic
The hyperbolic functions represent an expansion of trigonometry beyond the circular functions. Both types depend on an argument, either circular angle or hyperbolic angle. Since the area of a circular sector with radius r and angle u (in radians) is r u/2, it will be equal to u when r = √2. In the diagram, such a circle is … See more 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, … See more Hyperbolic cosine It can be shown that the area under the curve of the hyperbolic cosine (over a finite interval) is always … See more The following integrals can be proved using hyperbolic substitution: where C is the constant of integration. See more The following expansions are valid in the whole complex plane: See more There are various equivalent ways to define the hyperbolic functions. Exponential definitions In terms of the See more Each of the functions sinh and cosh is equal to its second derivative, that is: All functions with this property are linear combinations of sinh and cosh, in particular the exponential functions $${\displaystyle e^{x}}$$ and See more It is possible to express explicitly the Taylor series at zero (or the Laurent series, if the function is not defined at zero) of the above functions. The sum of the sinh and cosh series is the infinite series expression of the exponential function See more WebUsing the definitions of hyperbolic functions in terms of exponentials show that sech^2(x) = 1-tanh^2(x)
