Stochastic Integrals and the Ito Formula,Example 3.6 illustrates that the basic definition of Ito integrals is not very useful when we try to evaluate a given integral. This is similar to the situation for ordinary Riemann integrals, where we do not use the basic definition but rather the fundamental theorem of calculus plus the chain rule in the explicit calculations.

The Filtering Problem, of ... Similarly to the 1-dimensional situation (3.20) there is an explicit several-dimensional formula which expresses the . interpretation of (6.1): . in terms of Ito integrals as follows: . (See Stratonovich (1966)). From now on we will use the Ito interpretation (6.2).
