Survey of Undergrad Math

  1. Apr 23, 2012 #1
    The answers are given at the bottom.

    For #3, it seems like they're describing a mapping from a closed set to an open set. We don't know if it's injective or homeomorphic.

    For #10, I is obviously true from the definition of n-tuples and the fact that it contains all n-tuples. III makes sense now, too. Apparently, I read it wrong earlier, so I think I'm fine on this one. Each basis can't be orthogonal if all entries are greater than 1.
