Aug 10, 2010 at 21:11 | comment | added | KConrad | To avoid any misunderstanding, I am not suggesting the formal defn. of derivative should come first in teaching, since of course the real derivative in calculus provides extra geometric intuition. | |
Aug 10, 2010 at 21:09 | comment | added | KConrad | Two comments. First, I don't agree that it is "much easier" to use the limit defn. of the real derivative to prove differentiation rules than it is to use induction for proving the same rules on polynomials over any (comm.) ring. Second, it is not legitimate to argue that the formal derivative was introduced only after calculus was developed. The formal derivative on real polynomials came first! See J. Grabiner, "The Changing Concept of Change: the Derivative from Fermat to Weierstrass," Math. Magazine 56 (1983), 195-206. On JSTOR this is at jstor.org/stable/2689807 | |
