Question
lim (1/x)=INF
where x->0+
  (i have used "INF" to indicate infiniti

please explain it

Answer
When dividing by a very LARGE number the result is very small,and when dividing by a very small number the result is very LARGE. Try dividing 1 by 10 and then try dividing 1 by .00001 and see what happens and so when x approaches 0 from the positive side, 1/x becomes very large, i.e., infinite.
