To find the limit
, we can use the given limit
.Let's rewrite the expression as:
Now, let
. As
approaches 0,
also approaches 0. So, we can substitute
for
in the limit:
Since
approaches 0 as
approaches 0, we can use the given limit
:
The second limit is equal to 1 as
approaches 0:
Now, we need to find the limit of
. As
approaches 0,
also approaches 0. So, we can use the given limit
again:
Therefore, the limit is:
So, the correct answer is:A.
