Homework Help: Proving expression with limits

  1. Oct 11, 2007 #1
    1. The problem statement, all variables and given/known data

    If [tex]a>>b[/tex] is it correct to say that [tex]\frac{b}{a} \rightarrow 0[/tex]

    Can we prove it with limits?

    you can say that if lim a-> infinity, that b/infinity = 0 because any number divided by an extremely large number (in this case infinitively large) is 0.

    Well we only know the relation between a and b! We cant know that a is very large, we know that a is much much greater than b.
