hi there Nuu.... uu... ria!!!

just for reference reasons, here is the graph of logx :


as we can see, logx will go to ∞ when x gets larger and larger.  but ∞ is not a number and consequently we cannot evaluate log(∞).  however, if we know what happens to x as it approaches ∞, we can easily compute the limit of logt.  here is how:

           lim(x->∞ ) logx
                    as x -> ∞, we know t = x -> (∞) = ∞
           lim(t->∞ )logt = ∞

hope this helps!!!

I would like to know, if the limit of a logarithmic funcation, lim(log(x)), when x --> infinity, is log(lim(x)) when x--> infinty, due to the logarithmic function behavior.

Thanks!
