    Finding the intersection of subspaces, and addition of subspaces

    span{u,v} represents all the combinations of u and v. (at least that's what i understand). and yes, span(u,2v) does contain v, and so can i multiply 2v by 1/2? and then have span{u,v} instead of span{u,2v}? if this is the case, then how do i find the intersect if F=span{w,v} seeing as w is not...

    Finding the intersection of subspaces, and addition of subspaces

    Heres the question: Let {u,v,w} be a linearly independent set of vectors of R^4. Let E = span{u,2v} and F=span{w,v}. Find EnF and E + F. i really have no idea other than i guess if 1/2u=w and v=v, then the EnF can be defined by that, but I'm not sure if that is right! :(
