@zepdrix can you help?

analysis? what does that mean? like you're trying to find critical points and such? :o

Yeah, sorry... Max, min, inflections..

Didn't know you can do that.. :/

Maybe not the most relevant if we just want max and min values :) but still kinda neat.

blah i dunno XD

hmm, interesting. So we know a critical point is x=1 right?

yah it looks like x=1 and x=-1 are critical points. :D

If i did my math correctly.. :O i hope.

yeah, x=1, -1... But what about domain issues?

Oh good call, -1 isn't in our domain :3 so we don't care about that value.

hmmmmm... i'm a little bit confused... what IS our domain?

That looks right, automatically the end points of our domain are critical values right?

Because we can't attach a tangent line there?

Maybe that's what you were saying though :)

Hmm interesting :D

I just found this: http://screencast.com/t/b4Jx1qLkQlo

cool :O

oohhh.. okay... now to move onto the second derivative tests... :)

\[\huge f'(x)=-(x-1)^{-1/2}(x+1)^{-1/2}\]

right :D

If you need to see my steps, I can post them :D

Yep got that too!

so... When f''(x) = 0
x = 0

barely.. lol

XD

haha, yeah.. been there before.. I prefer the TI

oh fair enough c:
