Homework Help: LaPlace Transform question #2

  1. Apr 13, 2013 #1
    I'm not sure about the answers to parts of the limit step of the work. Can you explain what the answer to that step should be?

    Use that s>4. If that's so, then both of the exponents are a negative number times b, and so do go to 0 as b->infinity.
