For each of the following forms determine whether the following limit type is indeterminate, always has a fixed finite value, or never has a fixed finite value. In the first case answer IND, in the second case enter the numerical value, and in the third case answer DNE. For example

To discourage blind guessing, this problem is graded on the following scale
0-9 correct = 0
10-13 correct = .3
14-16 correct = .5
17-19 correct = .7
Note that l'H\^opital's rule (in some form) may ONLY be applied to indeterminate forms.
