SUMMARY

The discussion centers on proving the limit expression \(\frac{b}{a} \rightarrow 0\) under the condition that \(a >> b\). Participants confirm that as \(a\) approaches infinity, the limit of \(\frac{b}{a}\) indeed approaches 0, based on the principle that any finite number divided by an infinitely large number results in 0. The key takeaway is that the relationship \(a >> b\) suffices to conclude that \(\frac{b}{a}\) approaches 0 as \(a\) increases without bound.

Homework Statement



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

Can we prove it with limits?
 
Physics news on Phys.org
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 can't know that a is very large, we know that a is much much greater than b.
