Didn't you post this exact question and get an answer here?
I am having trouble verifying the following problem:
If the functions and are defined on with , and where and , prove that
Here is what I have tried to do
Suppose is a sequence defined on which diverges to .
At this point I need to show that the sequence diverges to , thereby confirming that the sequence converges to L as .
How can I show that the sequence diverges?
