I was posed this problem on another forum by a first year and for some reason I'm struggling

lim x-> 1 from the left of

Could someone provide me a precise way to show the limit goes to infinity?

I use a theorem : let from left as k->infinite , and f be continuous if , as

clearly , is a continuous on and let converges to 1 from left.

And this is infinite as k->infinite - January 13th 2009, 05:14 PMMacstersUndead

Since a divergent sequence can has a convergent subsequence ,the sequence i used is not arbitary.

think simple: approaches 0 from

__negative values__because and approaches so the limit is - January 13th 2009, 05:51 PMMacstersUndead
