A Taylor series is a collection expansion of a duty around a point. A one-dimensional Taylor series is an growth of a actual function

If

*
, the development is recognized as a Maclaurin series.

Taylor"s theorem (actually discovered first by Gregory) states that any function satisfying certain conditions have the right to be expressed as a Taylor series.

The Taylor (or more general) series of a function

To derive the Taylor series of a role

(Abramowitz and also Stegun 1972, p.880), so the maximum error after

is likewise periodically taken to describe the remainder as soon as terms up to the

st power are taken in the Taylor series (Whittaker and Watchild 1990, pp.95-96).

Taylor series deserve to additionally be defined for features of a complexvariable. By the Cauchy integral formula,
