WebNov 1, 1978 · The Budan-Fourier theorem on the isolation of roots uses a sequence of derivatives, f(x), f(1)(x), ..., f(n)(x). The procedure is similar to that used later (1829), by Sturm, to calculate the number of variations of sign (as defined by Descartes' rule) in the two sequences of real numbers obtained when x is replaced by the real numbers p and q ...
