Etymology

[edit]

Named after Scottish mathematician Colin Maclaurin (1698-1746), who made extensive use of the series.

Noun

[edit]

Maclaurin series (plural Maclaurin series)

  1. (calculus) Any Taylor series that is centred at 0 (i.e., for which the origin is the reference point used to derive the series from its associated function); for a given infinitely differentiable complex function , the power series .

      Analytically there are, of course, two Jacobi series branching off the Maclaurin series, but they are geometrically and physically identical, and involve only an interchange of a and b.

      If the Maclaurin series of f and g converge for |z| < r and g(z) ≠ 0 for 0 ≤ |z| < r, then if the Maclaurin series for f is divided by the Maclaurin series for g by long division (as if the series were polynomials), the resulting series represents f / g for |z| < r.
    • 1997, Frank Smithies, Cauchy and the Creation of Complex Function Theory, Cambridge University Press, page 203:
      It was almost as a by-product of this work that, in the first Turin memoir, he proved the convergence of the Maclaurin series of a function up to the singularity nearest to the origin (Section 7.5); it was in this context that he created what he called 'calculus of limits', later known as the method of majorants.
