Hi, is it possible to evaluate 1/(x-1) at x=1 by any means?
As x gets closer and closer to 1, the numerator remains 1 while the denominator gets closer and closer to 0- the entire fraction (in absolute value) gets larger and larger- there is NO limit.
You can't even say " ".
If x< 1, the denominator is negative so .
If x> 1, the denominator is positive so .
