Asymptotic methods

    Asymptotic methods....

    hi all...
    i am really frustrated with the asymptotic methods.
    I just don't understand where those asymptotic expansions come from...
    While I know the definition of a asymptotic series, but the author of the books seems always assume a series and eventually claim that is an asymptotic series to a function without going through the definition:
    The remainder is much smaller than the last retained term in the series...

    can someone explain the standard procedure of obtaining a asymptotic series solution to the simplest equation...?
