2. TAYLOR SERIES THEORY
It is common practice to use a finite number of terms of the
series to approximate a function. The Taylor series may be regarded as
the limit of the Taylor polynomials.
Taylor's theorem (actually discovered first by Gregory) states
that any function satisfying certain conditions can be expressed as
a Taylor series.
A Taylor series is a series expansion of a function about a
point. A one-dimensional Taylor series is an expansion of a real
function about a point is given by
