To quickly assess the difficulty of the text, read a short excerpt:
1. Using derivatives of higher order, we can generalize the Law of the Mean as follows : In the interval 21 = (a, 5), let f(x) and its first n - 1 derivatives be continuous. Let / (B) O) be finite or infinite ivithin 51. Then for any x in 51, n 1 where a256 DIFFERENTIATION As in 397, we introduce an auxiliary function 11 (2 where J. Is independent of w. This function is obviously a con tinuous function of u in 21 for any z in 2J. Differentiating with respect to w, we get, observing terms ...cancel in pairs, ~ l f^u) + A\, (3 , ft/ X for any w within 21. Thus the derivative of #(w) is finite within 21. To apply Rolle s theorem to #(w), with reference to the interval 33 = (a, z), it is only necessary to determine J. In 2) so that #O) = #O). But obviously 000-0. We therefore suppose A so chosen that (4 Then by Rolle s theorem, there is a point a < c < x, such that This in 3) gives c !r c ?""V w oo-^=o. (5 /v ^~~ J- As c =?t= z, the first factor in 5) is not 0. Hence the parenthesis is 0, which gives f w (c~)= A.
