My question is regarding the association between usecases and actors. There is a usecase diagram with 3 actors and about 10 usecases. Each actor has one usecase DIRECTLY out of him, but then other usecases branch out of this root usecase, through < > and < > and inheritance relations. If a question arises such as, "Name the usecases that affect Actor B?", how should you go about identifying them? Any input will be greatly helpful and appreciated. Thanks, Bala    More>>

There are no specifications for such a case in UML (as per my knowledge).
Suppose an actor "A" is associated with use case "UC-A" and this use case is extending some other use case, so we can say that use case "UC-A" is affecting the actor "A".
This is internal to usecase that what it is extending and on what it is dependent.
This might help to solve ur doubt.
