Re: Limits!
Hi anonimnystefy,
I find most of the limits yield to the techniques discussed here.
I'll post if I find something extraordinary!

Let x = 1/y. As x --> 0, then 1/y --> 0.
So y --> oo (or -oo).
The limit could be expressed as:
Notes:
--------
Step 2 to step 3 used the Binomial Theorem.
Step 3 through step 5 could use some
justification/details to support the
continued patterns of terms and expressions,
respectively.

hi gAr
Would you don't mind if i post a problem?It's just that i don't want the topic to get forgotten.

Absolutely!
Anyone may post limit questions here.

Re: Limits!
hi gAr
thanks.
here's one interesting limit:
i haven't encountered it yet and its kind hasn't been mentioned in this topic but it is one of the easier limits of this kind

Hi,
I too haven't done multivariable limits!

these posts will be answered when i count to infinity and back.Maybe i should consult Chuck Norris.

Re: Limits!
Hi anonimnystefy;
Is this one you want help on?
I have never done one but I know how the packages do them. I think they nest the limits:
Just plug x = 0 into the limit:
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Re: Limits!
the first limit does not exist and the second one is correct but i tried to make a very bad joke.

Re: Limits!
the one in #140 doesn't exist because when we aproach it from two different paths it has different values.it is similair to the situation with one variable limits when the left and the right limit do not match up.
