I need to determine whether diverges at x= -4, and x=4.
I want to use the alternating series test, but my book defines it as starting at n=1, not n=2 like in my problem.
Can I use the test as it is? Do I need to manipulate it? If I need to manipulate it, would this be a valid manipulation?:
I'm fairly certian it is, but I'm still a tad bit shaky with these.
