Homework Help: Find a basis for a module

  1. May 14, 2007 #1
    1. The problem statement, all variables and given/known data
    Given a few vectors that span a module space, how do you find a set that is a basis for this spanned space consisting of entirely different vectors to the original spanning vectors?

    3. The attempt at a solution

    I assume you find what kind of space is spanned by the vectors first. Then determine a bases for that space. But how do you determine the space spanned by the vectors? i.e determine the space concretely?

    What on earth does 'concrete' mean? You've been doing this for years in linear algebra - row reduce the vectors until you get something you like. Bear in mind to only do operations invertible in the ring you're dealing with. A concrete example would have really helped, by the way.
