Taylor’s theorem approximates the output of a function f ( x ) around a given point, such as x = a , by providing a k-times differentiable function and a polynomial of degree k, which is known as the kth-order Taylor polynomial. In other words, the first-order Taylor polynomial prov...
In an era before automobiles, when steel rails handled nearly all interstate and intercity travel, the interurban concept seemed viable, in theory. There was also the added perk of providing some freight business. As interurbans expanded they did indeed initially prove popular offering quick service...
