Order notation

  1. May 14, 2014 #1
    Hi,

    Is there a better way to write this?

    'terms of order [itex]O(R^{-Y})[/itex] where [itex]Y>1[/itex] are neglected'

    I feel like this is a bit clumsy.

    Thanks for the help!

    Yeah that's correct, if I am understanding little 'o' notation correctly I believe it's equivalent to write:

    'terms of order [itex]o(R^{-1})[/itex] are neglected'

    It is simpler to write it in terms of what orders you will accept.
    Note, you wanted Y>1, so Y=1 (order -1) was accepted.

    Take terms in (1/R) to 1st order.
