Hi all.. Got Calculus? :beer:

Okay two problems..


first one;


evaluate the limit: lim as x -> 9 for (1/x - 1/9) / (x - 9)


evaluate the limit: lim as x -> 9 for (9 - x) / (3 - {sqr root of x** )



btw, I already know the answer(s) of course.. I just want to see if you're anywhere near as smart as I.





Thankyou much.

You guessed right! .. ANy chance you could guess right the solutions as well -? . . Man, I don't know how to do that kind of algebra. I was guessing 0, 1, -1, 3, -3, 1/9, -1/9 and DNE.. and I only have three guesses left for the first one, and four guesses left for the second problem for this on-line homework thing. I need a life line.

You could spend your time more constructively trying to read the book and figure it out, or google search tutorials rather than wasting time in here trying to get us to do it for you.

It's only 'wasting time' - if you guys don't do it. So PLS, stop wasting my time! (I don't have that much more time for you to waste). thanks..

If you don't get it by 7:30, I'll think about giving you the answers. It'd be nice if you tried to work through it.

Here's a couple hints: for the first one, find a common denominator in the numerator (that sounds complicated). I'll be willing to bet you'll get something to cancel with the 9-x on the bottom

as for the second one, does thinking of a problem like finding the lim as x goes to 9 for (9-x^2)/(3-x) help?

Thankyou JoeMetal.. I was starting to lose faith in foo. Btw, what do you think about all these other worthless spectators? Are they 'worthless', or what?

Can you at least try to work for it? I'm not just going to give out answers for free.

If I was still in high school, I could probably help you out, but I'm lost touch with the math gods...

No, I never lie.. Sometimes I might exaggerate. Sometimes I may elude to something which isn't 'entirely' the actual truth. But you'll never catch me in a lie.

You don't know the answer, so isn't that a lie?
