Web10 Apr 2024 · We study the elliptic sinh-Gordon and sine-Gordon equations on the real plane and we introduce new families of solutions. We use a Bäcklund transformation that connects the elliptic versions of sine-Gordon and sinh-Gordon equations. As an application, we construct new harmonic maps between surfaces, when the target is of constant … WebThey are found by taking the first identity, {eq}\cosh^2 x - \sinh^2 x = 1 {/eq}, and dividing it either by the first or second term.

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, sinh t) form the right half of the unit hyperbola. Also, similarly to how the derivatives of sin(t) and cos(t) are cos(t) and –sin(t) respectively, the derivatives of sinh(t) and cos… WebIdentities sinh (−x) = −sinh (x) cosh (−x) = cosh (x) And tanh (−x) = −tanh (x) coth (−x) = −coth (x) sech (−x) = sech (x) csch (−x) = −csch (x) Odd and Even Both cosh and sech are Even Functions, the rest are Odd Functions. …
