Differentials*
Published online by Cambridge University Press: 03 November 2016
Extract
In the teaching of the Theory of Differentials the really difficult and important problem is not “how shall we teach a given theory?” but “which theory shall we teach?” There are, in fact, a number of rival theories, none of which has met with any general measure of acceptance. In these circumstances, the critical problem of considering the rival merits of these theories is much more urgent than the pedagogical problem of presenting them to students.
