Math rant

;p PM'ed, i could look over them now so im a little ahead in the class.

Structural engineer (fresh outa grad but STILL not done w/ my thesis  ) here.

What textbook are you using? Wont' help you much if I dig through my text book and it's the same one you're using.

Oh yeah, that last one = WTF  It's only a 3 line question and it still has at least 6 words I don't recognize.

we arent really using a text book. i just haveone as reference. Everything comes out of his mouth whic his why i dont get this stuff. He goes off on tangents worst than I  do. lol talking about victorian english and his home town of birmingham for about half the class.(hes also Jamaican so it makes him have a very intresting personality and teaching style cause hes also english)

man chem-e's are the sickest people in the head....next to physicist....  how many engineers do we have on this forum anyway?

I'm an engineer. There are a lot of us here.

I play an engineer on TV.

Heh

I got my A.B. as a math major


It doesn't get any easier man


Good luck... you'll figure it out.

best website ever for upper level math!

Question for anyone who knows...

if were looking at a  series such as this one except the numerator was flipped to the denominator, could we still cancel out to 5/3?

Frenchie says "I forget how to do this with a double integral, but there is a down and dirty way.  The intersection of the two should be two circles, x2 + y2 = 1 in the planes of z = +/- sqrt(3).  So you get a cylinder, radius = 1, height = 2*sqrt(3).  Then you have to integrate Pi*[sqrt(4-x2)]2, or just Pi*(4-x2) from sqrt(3) to 2 (Remember the disk method of finding the volume of a sphere from Calc II).  Oh yeah, and the integral has to be multiplied by 2, because the damn thing has two ends on it."


meh

[He Man]

where does the root 3  come from?

If he is doing it half a  circle then it should be zero no? 

cause thats what i basically did.  and im stuck at. lol

i just took a look at his equation again. the top part of the capsule cannot be a circle of x^2 +y^2=1. because for that to be true, it would need to be a circle, when in fact it is just a slice of a bigger circle whos radius is 2. So in reality it is just a dome.

edit: CRAZY turn of events.

After teaching my self everything on that website about infinite series. something started happening. I felt like i saw all those numbers before....

this whole test is from that website i posted above scattered from various tutorials.

Lol, so your teach cheaped out and stole someone else's stuff for his test? So that means that you've got the whole test's answers?

This is how I roll

It was what i thought. its 2:15am.. and i just finished 80% of the test.

Everything is from the website basically. Except instead of X^2+1 its (x+1)^2...now it may not look like much, but it could throw a problem into the gutter and make it a) unsolveable, b) very make the beast with two backsing messy or c)pisses me off.

He has a habbit of making stuff up from his head on the board and things dont always work out the way you want it too. (inmagine 20 feet of board surrounding 3 sides of the room filled with his nonsense).

Anyway, the website i linked you guys to had enough information to teach me about everything on the test, and its been about 2 days worth of work (8+hours) to learn everything.


HOWEVER... i still cant get that capsule shaped question. LOLOL its the only thing left on hte test i for the love of god, cannot figure out. I killed almost a whole ream (500 sheets) of white paper. its all over my floor, on my bed. etc. probbaly 50 of those sheets are trying to figure out htat problem. :/

anyway, problem 1, was exactly as worded. problem 2-6 (not inlcuding 3, the capsule question) took about ~6 hours to learn and do. not bad!

okay now im back to trying to figure out problem 3.....and then physics studying and im gonna make myself a pizza and call it a morning. does dominos deliver now?


dude is that really you?

because i drafted an idea of a tat I want, and its 3 triangles with parallel sides (to make it have some width) that are filled in with mathematics... lol
that tat is make the beast with two backsing AWESOME man. though i have no idea what it represents, i can only read it. WTF IS A GRADIENT SQUARE!!!!!

431am.

IM DONE. (not finished, aka im tired gotta wake up in 2 hours!)

Electrical Engineer here.  As I started reading the thread, I started to miss the high level math classes, they made me feel a lot smarter than the mindless crap I do at work now.... but as the thread progressed and I watched He Man's slow descent into a familiar state....  I'd prefer to find mental stimulation elesewhere.  Best of luck.

All you have to do now is to commit it to memory so that you may instantly recall it whenever required (which probably will be very infrequent)
