History of trigonometric functions
WebTrigonometric functions can also be defined as coordinate values on a unit circle. A unit circle is a circle of radius 1 centered at the origin. The right triangle definition of trigonometric functions allows for angles between 0° and 90° (0 and in radians). Using the unit circle definitions allows us to extend the domain of trigonometric ... WebApr 18, 2024 · So as you can see, all of the trigonometric functions are closely related to the exponential function, and thus to e. The circular trigonometric functions have these alternating signs, which are best explained as a purely imaginary argument to the exponential function.
