Limits and continuity

  1. May 25, 2013 #1
    Lim(x-->0) x/a[b/x] can be written as x/a(b/x-{b/x})

    how can we write this as
    (b/x -b/a({b/x}/{b/x}))?

    Do [square] and {curly} brackets have some special meaning to you? Because
    [tex]\lim_{x \to 0} \frac{a}{x} \frac{b}{x} \neq \frac{x}{a} \left( \frac{b}{x} - \frac{b}{x} \right)[/tex]
    doesn't really make sense to me.

    Sorry, they are very common in my exercise books
    square brackets mean the greatest integer value of the variable within and the curly brackets mean the fractional part of the variable within.

    Your question is a little confusing. You have a term {b/x}/{b/x} (=1??). So it seems you are asking about (b/x - b/a)?
