Indeterminate Forms Consider the following three limits 1 ) x x x 2 0 lim 2 ) x x x 0 lim 3 ) 2 0 lim x x x Since 0 lim lim 2 0 0 = = x x x x , in each case we have a quotient like 0 0 , but 0 lim lim 0 2 0 = = x x x x x 1 1 lim lim 0 0 = = x x x x x x x x x 1 lim lim 0 2 0 = does not exist We call the form 0 0 indeterminate since one cannot determine what the limit will be.
