OK math people

[stoops the eternal pimp]

which one of ya want to help me take this Calculus test I m doing online?

[crawfish]

I'll help.










if you don't mind failing.

[stoops the eternal pimp]

I don't need assistance in that area..I ve got it covered..Thanks for offering

[SoonerInKCMO]

I took Calculus I-III in 1987-88... I'd offer to help but I'd probably be as useful as crawfish. :D

[Ike]

Take a derivative

Do an integral

just do one of those two things. If you find you are having a hard time doing either of those, then your problem is probably more with algebra than with calculus.

[Frozen Sooner]

I went through Engine Math I, but I don't think I remember a whole lot.

[GottaHavePride]

Six years ago I could do calculus in my head. Abstract linear n-dimensional algebra was what I failed.

But I'm a lot rusty. And at work. ;)

[stoops the eternal pimp]

My problem is that I haven't had a math class since 96 and honestly, I cant remember half of it...doing the derivatives now Ike

[Howzit]

I went through Engine Math I, but I don't think I remember a whole lot.

Ditto.

Shoot, I have trouble refreshing my memory on HS algebra. The weird thing is that when I look at examples I can see what they want done. But reading the problem and interpreting...no way.

[olevetonahill]

Just Peem the ?s Ill Fix Ya right up !:D

Well, when one learns Calculus as Newton was developing it, we can't really expect him to remember much of it now. :texan:

[sooner_born_1960]

Right now I'm helpling my 9th grader with AP geometry. When she get to Calculus, I'll get back with you.

You know Vet..I made the thread because I knew you could help

[olevetonahill]

Shoulda gone to FSU...I hear they have people that are more than willing to help with online tests...:O

[texas bandman]

I had High school algebra, so I guess I can't help, but if you ever need any help on how to resolve a German, Italian or French 6th chord give me a holler. :D

[crawfish]

You've got me by two years. :D

[crawfish]

I had trouble remembering a whole lot when I took it. :D

[yermom]

derivatives? like in limit form or the easy way?

[shaun4411]

i got a B in Differential Equations back in 2003. probably wouldnt be much help now. i havent taken calculus since 2002. man i feel old.

[yermom]

i got an A in Ordinary Differential Equations in '97, took my last Calculus class in '96. Physical Math was the real beast. i think OU math profs like failing people :eek:

but i ended up taking that stuff so much, and using it in my other classes, i think i have a pretty clear memory of a lot of it

[SoonerInKCMO]

I only made it thru Calc II - so you'd prolly be more help than me.

[olevetonahill]

Wait I got to get another natty
Ok Now what wuz the Question ?

[stoops the eternal pimp]

Wait I got to get another natty
Ok Now what wuz the Question ?

Find the relative extrema of the function if they exist.

F(x) = x + 1/x^2 + 3x + 3

AND GO!

[proud gonzo]

i could have helped you up through Calc II if you'd asked... 5 years ago.

[proud gonzo]

Find the relative extrema of the function if they exist.

F(x) = x + 1/x^2 + 3x + 3

AND GO!dude... wouldn't that be f(x) = 1/x^2 + 4x + 3 ?

[stoops the eternal pimp]

i could have helped you up through Calc II if you'd asked... 5 years ago.


Believe me, I would have asked you....

[SoonerInKCMO]

Find the relative extrema of the function if they exist.

F(x) = x + 1/x^2 + 3x + 3

AND GO!

Solve F'(x) = 0 for x.

That's pretty much all I remember.

[SoonerInKCMO]

And that could be wrong. :D

[yermom]

dude... wouldn't that be f(x) = 1/x^2 + 4x + 3 ?

maybe the first term is supposed to be x^3?

is that supposed to be x^-2? that seems kinda out of place...

is it like

x+1
------------- ?
x^2 + 3x + 3

[stoops the eternal pimp]

x+1

x^2 + 3x + 3


yeah thats it!

[yermom]

how far have you gotten?

have you graphed it? http://www.walterzorn.com/grapher/grapher_e.htm f(x) = "(x+1)/(x^2 +3x + 3)"

if you look at the graph, there is a minimum at -2 and a maximum at 0, this is where f'(x)=0 f'(x) = "(-x^2-2x)/(x^2 + 3x + 3)^2"

[Frozen Sooner]

yeah thats it!

OK, f(x)=(x+1)/(x^2+3x+3)
let u(x)=x+1, u'(x)=1
let v(x)=(x^2+3x+3), v'(x)=(2x+3)

f(x)=u(x)/v(x), by quotient rule f'(x)=(v(x)u'(x)-u(x)v'(x))/(v(x)^2)

After simplification, f'(x)=(x^2+2x)/(x^2+3x+3)^2

At f'(x)=0, x must equal either 0 or x^2=-2x x=-2

Ta da!

[Frozen Sooner]

Dang it, I took longer, but I showed my work and didn't use a calculator!

[yermom]

i didn't use a calculator either :D

i left the derivative to the reader :P

[stoops the eternal pimp]

2 evil geniuses

[Frozen Sooner]

Jeez, yermom, finding the derivative is the crux of the problem. I mean, if he just turned in his test and said "Yeah, this is what the derivative is and I punched everything into a graphing website here's what the minima and maxima were" I think he'd be getting an F. Obviously they were trying to get him to demonstrate knowledge of the quotient rule.

;)

Don't knock the quotient rule. It's gotten me action before.

Seriously.

[stoops the eternal pimp]

For you Mike I am now playing the Notre Dame Victory March in my office

[SoonerInKCMO]

Don't knock the quotient rule. It's gotten me action before.

Seriously.

You hang with some seriously nerdy chicks.

[Frozen Sooner]

Are you running around with your fists thrust in the air and making the "V" sign?

Because otherwise it's no good.

[Frozen Sooner]

You hang with some seriously nerdy chicks.

Or some chicks that desperately needed help getting through Calculus.

[yermom]

i'd say the more important part is knowing what the nature of extrema is and what it really means when f'(x)=0

well, that and that the Quotient Rule is a panty dropper. i wish i would have learned THAT in Calculus

[Frozen Sooner]

Yeah, well, you'd be wrong. :P

[BigRedJed]

You nerds are only posting in here to try to keep the post count ahead of my awesome meth thread.

[sooner_born_1960]

OK guys. Lets not celebrate too much. That was just the first problem, and it took 2 and a half hours.

[Frozen Sooner]

Well, it would have helped if he had actually asked the question correctly. Sheesh.

[stoops the eternal pimp]

Are you running around with your fists thrust in the air and making the "V" sign?

Yup and printing YOUR GOING TO HELL! pamphlets...

And it would help if I asked the question right...

That was the last question on test...made a 80....good enough for now..

[sooner_born_1960]

Never mind.

[SanJoaquinSooner]

save the hardest one for me.

[OCUDad]

save the hardest one for me.The hardest what, Big Boy?

[BigRedJed]

I saw that one coming.

[BigRedJed]

Good lord, does EVERYTHING on this board sound like gay humor today?

[OCUDad]

I saw that one coming.:eek:

[BigRedJed]

See above post. I saw that one coming too. :D

[SoonerInKCMO]

Today?

[BigRedJed]

Good point.

[Howzit]

For the record, I didn't initiate it.

[BigRedJed]

There's a first time for everything.

[mdklatt]

Right now I'm helpling my 9th grader with AP geometry.

You can get AP credit for classes that are required for HS graduation? :confused:

Damn, I could have had a college degree before I even started.

[soonerboomer93]

i'm glad i did enough drugs to forget all that ****

especially when i used to do it in my head

[Vaevictis]

Don't knock the quotient rule. It's gotten me action before.

Quotient rule == waste of brain space.

Just remember the product rule, and use a negative exponent.

[Frozen Sooner]

By that token, the whole of math is a waste of brain space. Start with 0 and just derive the rest as needed.

[Vaevictis]

By that token, the whole of math is a waste of brain space. Start with 0 and just derive the rest as needed.

That's a good idea :D

Isn't that pretty much what we did? Although, zero came much later, IIRC.

[Frozen Sooner]

Heh. Good point. I think the concept of 0 didn't come along until around 1100CE. Then again, notice not a lot of great abstract math was getting done until then...

edit: never mind, I guess that the Babylonians had the concept, they just didn't have a true symbol for it. The 1100CE figure came from when it got imported to the West.

You only need to know 10 things in tech support:

Why do computer geeks get Halloween and Christmas confused?

... because Oct 31 = Dec 25.

[yermom]

oh my.

[Vaevictis]

I'm here all week.

Don't forget to tip your waiters.

I entered college with 45 hours of credit, and most of my general-ed requirements out of the way.

9 yers later I have an actual job. And I can misspell yers.

For geometry, it's actually a pre-AP course: one in line to prepare for AP Calc.

In math you can earn college credit via AP Stat, AP Calc AB or BC.

I hate myself for understanding this. :O

just embrace the geek. it's easier that way

you just get credit for the test. can you take the test without taking the class?

Geometry isn't generally required to graduate either though.

i took AP Calculus, Computer Science and English in HS

the English didn't go well. i still wish i would have taken the test though...

i violated the Calculus test :D

the CS (Pascal) test was a little tougher

[Frozen Sooner]

Heh. I took Pascal as independent study my junior year. On a Mac.

I remember about 0 of that .

[mdklatt]

Probably.

Hmmm...I'm pretty sure it is in Texas.

[yermom]

it wasn't when i was in school. people could take "Business Math" or some ****

[Ike]

Heh. I took the same class I think.

I too remember 0 of it.


However, It did do a decent job of preparing me to learn other languages easily
