NSX

SHould that be f'(x)? f"(x) is the concavity testing..

Just like Tom said; but you've got to be careful sometimes. Use the first derivative test to check for critical points, b/c sometimes the derivative may yield a MAX or a MIN; you may also have to check the restrictions placed upon the model.

lol She'll be like:

What's the formula? I'll try asking my chem teacher about it...hahaa

How'd you go from that step to the other? edit: You'll have to excuse my cheesed arrow there. =)

Well, to me; Physics seems alot more organised than Chemistry, maybe b/c its been around for a while. While chemistry is still a bit iffy... ie. For every 10 questions I ask in Chem to my teacher, the answer to 9 of them is Well, that's just the way it is. WHile in Physics, there's a logical reply.

ooh!!! I never thought of that!

Ewww...Chemistry!!!!! hahaa; It's okay, I had to learn it from a textbook; principal quantum numbers, secondary quantum numbers, spin quantum numbers, & 1 more? ugh; I hate chemistry.....probably b/c my teacher seemed like she was constantly pulling stuff out of her arse:rolleyes:

That's cool; lots of practice with implicit differentiation helps...lol So with the original thingy; did you mean: :lint: d(ax^n)/dx ?

So...when we print red ink onto a piece of paper w/ a printer, it shoots out atoms that absorb only the green & blue part of the spectrum? SO that we see red?

Well, I'm going into that; and its just a interest right now; like, dave helped me to prove some of the other trig identities last time; but I'm still missing the link b/t Calculus & Geometry...

So ax^n is your original funx. Is dx is the derivative of the original funx?

ooh...I gotta jot it down. hehe ooh...I see; cool thanks.

I haven't learned integration yet; care to teach me? But I was just thinking, if you have an infinite number of sine & cosine funxs, wouldn't they just nullify each other causing 0 amplitude? Or am I missing something here?

hm...I don't get those parts..hehe At what point do you learn those trig. integral identities? Or integration even?

OR we could find some way to make food replicators like in Star Trek

Can someone clarify or explain what the Fourier Series is? From what I understand, its a way in which periodic funx can be expressed as a sine & cosine funxs together; However, seeing as how my knowledge in Calculus is limited to Grade School Advanced Functions & Introductory Calculus, I'm just like when I see sites like http://www.nst.ing.tu-bs.de/schaukasten/fourier/en_idx.html#DIRI & http://mathworld.wolfram.com/FourierSeries.html

Well, in Canada, there's a required Grade 10 Literacy Test needed for all students to pass in order to obtain their High School Diploma as well. The test was divided into 2 parts: Math & English Personally, I don't really have any problems with it, but the problem lies in the fact that there are alot of immigrants to Canada, especially those whose native tongue is not English. Everyone knows that the Asian style of teaching is much more rigurous than the one in Canada (I'm not sure how the education system is in the states); so most the immigrants pass the Math part with flying colours. HOwever, when it comes to the written English Comprehension part, problems begin to arise..

What about colour on paper? The e-'s are relatively stable, as its a solid...so they don't jump orbits & produce colour, or do they?

Well, that's what Grade12 Geometry & Discrete Math is like in Toronto...

Cool; so what's yours? Andromeda?

TNG!!!; hm..I'm the only one..What did you guys not like about it? How's babylon 5? I've never seen it yet..

whhops, or maybe it should go in the HW help part

Can someone check over my proof please? Thanks. I'm using the delta symbol to signify triangle Question: S is the midpoint of side QR of :delta: PQR. QT & RW are drawn perpendicular to PS or PS extended. Prove that QT=RW: Here's my sol'n: In :delta: QTS & :delta: RWS: 1. QS = RS (given) 2. Angle QTS = Angle RWS (given) 3. Angle TSQ = Angle WSR (Opp. Angle Theorem) 4. Therefore :delta: QTS :cong: :delta: RWS (Angle Angle Side) (State1, S2, S3) 5. Therefore QT=RW Thanks. It's for a hw presentation for Monday. I've attached a jpeg of what the question looks like:

Well...try pseudoscience. faf or blike will freak out if it's anywhere else
