Hi,

I'm having some problems with calculating quite a few limits, so I guess there's a concept I'm not getting...

Or:

How should I solve these?

first one is one == 1 :D

(hint: it's so u have to ... == and so on ... )

second is zero :D (first use L'Hospitals rule .... )

(hint: after first use of rule you should get and after second use you will get ..... )

third one is infinity :D (first use L'Hospitals rule .... )

(hint: after use of rule you will get .... )

That's what I thought, but I also read that infinity^0 = undefined ?

I see you've edited your post.

The first one: could you elaborate a bit further please? :$

I understand the second one. I was doing l'Hospitals, but I didn't notice I could rule out the 2x every time (stupid mistake)

I also understand the third one.

Thanks for your help so far! - Aug 12th 2010, 01:51 PMyeKciM

I did some more researching and I get it know. Although, shouldn't it be ln instead of log ?

Do you mean that log should be used as the notation for the logarithm with base e then?

'cause , and , but
