Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering if some one could check my understanding of limits please.

If a limit is presetned as say x << y or x >> y am I right in thinking that x or y can be ignored as they are small enough to be insignificant? So, for example, if I had equation which was

sin(x/y)

in the situation where x << y only values of y are significant and where x >> y then only values of x are significant.

Or do I have this completely wrong??

Cheers for any advice
