Any math studs? Calc 3 help needed!

onewhippedpuppy · 06-29-2005, 04:18 PM

If there's anybody that's just awesome at math, I need some Calc 3 help. I have a practice test that was handed out, but no answers, so I need somebody to work the problems so I have a key. I need to be able to figure this crap out, damn I hate Calc.

To this person I offer the grand sum of $20 for your time (hey, I'm a college student with a Porsche, it's the best I could do).

Well post the question..

I did real well in multivariablecalculus and Diff-Eqs

TimT · 06-29-2005, 04:25 PM

Also isnt there something about learning? before you take this test?

BRPORSCHE · 06-29-2005, 05:30 PM

My dad is really good at math, so if you were to e-mail me the question(s) I will just e-mail them to you, but the soonest I could get them back to you would be monday the 4th. He is in germany...lucky sob

might help if I add my e-mail

The first derivative of mass x velocity is 1/2 mv squared, which is why its the velocity that makes the difference in a wreck, not the mass of the vehicle. That's about all I remember from calculus.

It's multiple problems Tim, kind of a challenge to post on Pelican. Also, when you're practicing for an exam, don't you find it helpful to know if you're working the problems correctly? This being a summer class isn't helping matters either, nor is being enrolled in 11 hrs of summer class.

Tom, I'll email you a scan of the practice test, if your dad has time I greatly appreciate it, if not no big deal.

onewhippedpuppy · 06-29-2005, 05:39 PM

Yeah, you get much past derivatives and it's into stuff that I'll probably never see again, even as an engineer. If it ever turns up, then it's off to the computer math program I go!

I discovered the key to calculus in Calc I (and got me through III with straight As): do problems EVERY SINGLE DAY. It is a process, not an answer.

you will never use it again.

but todd is right, with cal3, you got to work those problems. are you in the modern class where they really emphasize the graphing calculator? it has been too long for me, i will be no help.

Especially when taught by a math major. Those guys are awesome at remembering/regurgitating the process. (just don't ask them for an application of the tool ...that is calc.)

If you are an engineering student you WILL us calc. again.

Well, if you need help with reverse sexism in Jane Austen novels, you can always PM me...

That may have to wait until next semester.

Yeah Cliff, it's the one with all the funky 3d graphs. Now we're on to curvatures and other odd stuff.

I will use Calc again, just not Calc3. See Vash's above post, and he's an engineer. That's why it's so damn hard to find help with this crap, even our teacher was realistic enough to tell us that most people forget it 5 minutes after they learn it, and will never use it again. I love college.

The last time I used Cal3 stuff was to make a rough calculation of my 930 combustion chamber volume until I had time to get out a buret and measure it. I don't recall ever using it at work.

Send me an email at dmmartin@txgenco.com or a fax at 713-795-1411 and I'll take a shot at it. Keep your money for the Porsche.

Matt, if it makes you feel any better about having to learn this stuff, let me say; the reason abet accredited engineers make more $ than egr techs (even though they may not be smarter) is that the boss knows that the egr can(and will) quickly learn what ever is needed . .. regardless of interest. (the tech's usually are not so willing.)

So, uhmmm, yea-aahhh .... uhmmmm, we're going to need you to ahhhhh .... get used to it.

okay, then.

feel better?

I survived Calc 4, took all my Calc classes twice just to get C's. Why would anyone do this to an architect? Five credit classes meant lots of tutition - greedy private college.

Your statement about $$$ earned is mostly correct. It's the comment about the boss knowing the eng.
"can and will" that's bothering me (even though you prefaced your comment about the intelligence of the individual).

I've known many ABET accredited engineers that are pretty much just going through the motions after getting their first job.

Example? OK, several years ago I was participating a high level design review where one of my "accredited" coworkers threw up a view foil on the overhead that was full of calculations. The Director of the Program let this guy prattle on for about 5 minutes before he stopped him mid-sentence and pointed out that he had equated force with torque. Opps. Immediate dismissal from the review..."you have some more work to do" was the parting shot. This guy had forgotten the fundamentals and didn't even think to check or have someone else check his calculations. A 1st year statics/dynamics student would have nailed these simple calculations.

I also persoanally know many non-degreed eng. tech guys who jump head first into learning whatever it is that they need to solve the problem. Problem is...is that these guys are constantly having to prove themselves to be as effective as the degreed guys...it gets old after awhile.

IMHO, it's all a matter of motivation to do your best. Either you have it your you don't.

Ever read Ayn Rand?

its the process, not the material.

you engineers understand process, right?

This is why scientists are the real thinkers and engineers are just plumbers.

Now, where was that asbestos suit?

Yeah, us lowly enjuneers, we merely take the science and make it useable in everyday life...sometimes for a [gasp] profit[/gasp].

...and musicians are?

drug addict losers? But we get more chicks. And come on, at the end of the day, which will you look more fondly upon - the bridge you built, or the slightly overweight barely legal dirty blonde that you caught crabs from?

hmmm
