Hi All, I have a question on the Taylor's Theorem that is given in the notes in Chapter 10, page 13 that I was hoping someone might be able to answer. The theorem is given to the second order in the notes as follows (sorry for the ugly formulas!): df(xt) = f'(xt)dxt + 1/2f''(xt)(dxt)^2 + … The reader is then referred to the tables page 3 if unfamiliar with the above theorem. However, the theorem given in the tables looks very different: f(x+h) = f(x) + hf'(x) + 1/2h^2f''(x) + … I can't, through renaming variables and moving parts around, get from the first theorem to the second, does anyone know how these two formulas can be reconciled? Thanks very much!
