@halorazer any ideas? I'm working on practice exams..Been stuck on these last 2. The other one you answered. :)

anonymous · Answer

lnn is the natural log of n, correct?

anonymous · Answer

Yeah :)

anonymous · Answer

And is it ln(n) or is it ln^n?

anonymous · Answer

The first one. :)

anonymous · Answer

Well, when  the natural log of one is in the denominator, the denominator is equal to zero, which is a big no no in math. :p so that would explain why it starts at two.

anonymous · Answer

Hmmm...Okay so the answer is two? Im brain fried...

anonymous · Answer

I would look at this for help. https://answers.yahoo.com/question/index?qid=20090317104739AAAeHwx

anonymous · Answer

They say it diverges, and in all of my calculations that I put in, this in true. It increases to no specific number.

anonymous · Answer

$$\sum_{1}^{\infty} (-1^n-1/\sqrt{n}$$

anonymous · Answer

So its the same with that? (-1)^n-1/sqrt(n) not that hoopla of a mess above :P

anonymous · Answer

From n=1 to infinity
