WebJul 23, 2024 · We will thus need to use trigonometric identities in order to rewrite the expression in terms of angles that we know. Preliminaries In this article, we will be using the following trigonometric identities. Other identities can be found online or in textbooks. Summation/difference Half-angle Steps Review the unit circle. [1] 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 …
