The absolute value of X-1 is divided by the limit of X-1

The absolute value of X-1 is divided by the limit of X-1


The left limit is - 1 and the right limit is 1
LIM (x-1) ix-1i / (x-1) & nbsp; & nbsp; when X - → 1 + (x approaches from the right side of 1) & nbsp; = LIM (x-1) / (x-1) = 1
When X - → 1 - (x approaches from the left side of 1) & nbsp; & nbsp; = LIM (1-x) / (x-1) = - 1
