Hello, pratique21!
How are these indeterminate? .
I'll explain the first one . . .
Consider the function: .
We see that: .
But we have a theorem that states: .
. . Hence, we could say: .
Now consider the function: .
We see that: .
But: .
. . Hence, we could say: .
In general, we can show that can equal any number.
Therefore, is indeterminate.
