This may be a very basic question for this forum. I have just started to Learn Calculus. Please. help me with my question - Suppose I need to find the Limit of 1/x where x tends to 0 from positive side. I know from the graph of 1/x that answer is +Infinity. But if I apply Squeeze theorem to it and the greater function is 1 and smaller function is 1/(1+x). 1/(x+1) < 1/x < 1 : where x is always positive and tends to 0. The limits of these rightmost and leftmost functions at 0+ is 1. So as per squeeze th. the middle function is 1. Why it is different from the actual answer? Am I doing something wrong?
