Taylor|ˈteɪlə(r)| 1. Math. [The name of Brook Taylor (1685–1731), English mathematician, who published the theorem in his Methodus Incrementorum Directa et Inversa (1715).] Taylor('s) series, an infinite series of the form f(a) + hf′(a) + h2f{pp}(a)/2! + {ddd} + hn-1f(n-1)(a)/(n - 1)! + {ddd}, where f(i)(a) is the value of the ith derivative of a function f(x) at x = a; an analogous series for a function of more than one variable; Taylor's theorem, the theorem that a function f(x) can be approximated over any interval throughout which its first n derivatives exist by the first n terms of Taylor's series (with h = x - a) plus a remainder dependent on f(n)(a + θh) (0 ‹ θ < 1).
