A Useful Expansion in Applications of Determinants
Published online by Cambridge University Press: 31 October 2008
Extract
The expansion, in the form of a series, of the quotient of two determinants, in which the numerator determinant differs from the denominator in one column only, is moderately well known. It was found in 1825 by P. Schweins (see Muir's History, Vol. 1, pp. 171–2), and has many times since been rediscovered or proved ad hoc for particular applications.
