Eulers identity for sine
WebIn 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) … WebJul 15, 2024 · From Euler's identity one may obtain that, sin x = e i x − e − i x 2 i cos x = e i x + e − i x 2 However, it looks quite same to the hyperbolic functions such as sinh x = e x − e − x 2 cosh x = e x + e − x 2 where the …
