Re: Limits!

i just noticed when you posted these several problems that i don't know limits as much as i thought.

Re: Limits!

Hi all;


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!

Hi all,

-2 is correct.

Hi anonimnystefy,

If you show your steps, it would be easier to know whether you are approaching it in a good way, or you have come up with a better way!

Hi anonimnystefy,

You may avoid L'Hospital's rule here!



Now, try the next one!
