Question

Can you please explain me what is the difference between x---->0+ and x---->0- in limits ? I don't quite understand 100% so I thought I would ask just to make sure ?

Answer 1

limit x---->0+ means the right side limit,
limit x---->0- means the left side limit,

Answer 2

But what do you mean by "right side limit" and "left side limit" ? @Data_LG2

Answer 3

if this two sided limits are equal then the limit of the function exists.

example of limit that DOES NOT EXIST
