WebThe hyperbolic trigonometric functions extend the notion of the parametric equations for a unit circle $(x = \cos t$ and $y = \sin t)$ to the parametric equations for a hyperbola, which yield the following two fundamental hyperbolic equations: \[x = \cosh a = \dfrac{e^a + e^{-a}}{2},\quad y = \sinh a = \dfrac{e^a - e^{-a}}{2}.\] A very important fact is that the … 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 tangent to the hy…
