In mathematics, the Taylor series or Taylor expansion of a function is an infinite sum of terms that are expressed in terms of the function's derivatives at a single point. For most common functions, the function and the sum of its Taylor series are equal near this point. Taylor series are named after Brook Taylor, … See more The Taylor series of a real or complex-valued function f (x) that is infinitely differentiable at a real or complex number a is the power series where n! denotes the See more The ancient Greek philosopher Zeno of Elea considered the problem of summing an infinite series to achieve a finite result, but rejected it as an impossibility; the result was See more Pictured is an accurate approximation of sin x around the point x = 0. The pink curve is a polynomial of degree seven: $${\displaystyle \sin {x}\approx x-{\frac {x^{3}}{3!}}+{\frac {x^{5}}{5!}}-{\frac {x^{7}}{7!}}.\!}$$ The error in this … See more Several methods exist for the calculation of Taylor series of a large number of functions. One can attempt to use the definition of the Taylor series, though this often requires … See more The Taylor series of any polynomial is the polynomial itself. The Maclaurin series of 1/1 − x is the geometric series $${\displaystyle 1+x+x^{2}+x^{3}+\cdots .}$$ So, by substituting … See more If f (x) is given by a convergent power series in an open disk centred at b in the complex plane (or an interval in the real line), it is said to be analytic in this region. Thus for x in this … See more Several important Maclaurin series expansions follow. All these expansions are valid for complex arguments x. Exponential function The exponential function $${\displaystyle e^{x}}$$ (with base e) has Maclaurin series See more
