History of Maclaurin Series

History of Maclaurin SeriesMACLAURIN serial is the expansion of Taylor series about 0. So we fire say that it is a special case of Taylor Series.Where f (0) is the first derivative evaluated at x = 0, f (0) is the second derivative evaluated at x = 0, and so on.Maclaurin series is named after the Scottish mathematician Maclaurin.In mathematics, the Taylor series is a representation of a function as an in impermanent state of terms calculated from the value of its derivatives at a single point. The Taylor series was formally introduced by the English mathematician Brook Taylor in 1715. If the series is centered at zero, the series is also called a Maclaurin series, named after the Scottish mathematician Colin Maclaurin who made extensive use of this special case of Taylors series in the 18th century. It is super acid 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.HISTORYCol in MaclaurinBorn Feb 1698 in Kilmodan (12 km N of Tighnabruaich), Cowal, Argyllshire, ScotlandDied 14 June 1746 in Edinburgh, ScotlandColin Maclaurin was born in Kilmodan where his father, John Maclaurin, was the minister of the parish. The village (population 387 in 1904) is on the river Ruel and the church is at Glendaruel.EXPANSIONSuppose that f is a real function, all of whose derived functions f (r)(r=1, 2,) exist in some interval containing 0. It is then possible to write down the power seriesThis is the Maclaurin series (or expansion) for f. For many important functions, it can be proved that the Maclaurin series is convergent, either for all x or for a certain range of values of x, and that for these values the sum of the series is f(x). For these values it is said that the Maclaurin series is a valid expansion of f(x). The function f, defined by f(0)=0 and for all x 0, is notorious in this context. It can be shown that all of its derived functions exist and that f (r)(0)=0 for all r. Consequently, its Maclaurin series is convergent and has sum 0, for all x. This shows, perhaps contrary to expectation, that, even when the Maclaurin series for a function f is convergent, its sum is not necessarily f(x).The Maclaurin series of a function f(x) up to order n may be put in using series f(x,0,n).The nth term of a Maclaurin series of a function f can be computed in mathematics using series coefficient f(x,0,n) and is given by the inverse Z transform.Maclaurin series are the type of series expansion in which all the terms are non negative whole number powers of the variable. Other more general types of series include the Laurent series.Calculation of Taylor seriesSeveral methods exist for the calculation of Taylor series of a large number of functions. maven can attempt to use the Taylor series as-is and generalize the form of the coefficients, or one and only(a) can use manipulations such as substitution, multiplication or division, summing up or subtrac tion of standard Taylor series to construct the Taylor series of a function, by virtue of Taylor series being power series. In some cases, one can also derive the Taylor series by repeatedly applying integration by parts. Particularly convenient is the use of computer algebra systems to calculate Taylor series.Maclaurin series for common functionsfor -1
