Origin of trigonometric functions
WitrynaUnderstanding trigonometric functions is a pre-requisite for understanding topics in Newtonian physics, architecture, surveying, and many branches of engineering. WitrynaIn 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 …
