why does a limit exist only when left hand limit is equal to the right hand limit?
Asked by | 20th Aug, 2008, 05:58: PM
Left hand limit means you approach from left to a particular point,say,a.For y = f(x), there will be plenty real values
of x while approaching.You must find y nearing to f(a).Same thing happens when you approach from right vicinity.
The main concept is that the function sticks to a particular value which makes the limit exist .
