Itos lemma

I have a question about geometric brownian motion. dS = uSdt + /sigma/SdW and then we do log(S) and we want to found dlog(S). So we use Ito's lemma en I get the dt part of the lemma but I don't see To get the change in this type of f, due to small changes of these stochastic variables, you need to use Ito's Lemma. That's all it is. Your goal is to get the change in f due to small changes in the variables f depends on. For "sure variables", we uses Newton's differential formula (dunno if it has a name).

APPENDIX 13A: GENERALIZATION OF ITO'S LEMMA Ito's lemma as presented in Appendix 10A provides the process followed by a function of a single stochastic variable. Here we present a generalized version of Ito's lemma for the process followed by a function of several stochastic variables. Suppose that a function,/, depends on the n variables x\,X2

Ito’s lemma is very similar in spirit to the chain rule, but traditional calculus fails in the regime of stochastic processes (where processes can be differentiable nowhere). Here, we show a sketch of a derivation for Ito’s lemma.
