Hey,
I have an exam on wednesday which I pretty much have fuck all chance of passing so clutching at straws, do any of your mathematical/engineering types (hello *echoes*) know of any easy to cram resources for the following:
Advanced probability (think posisson, standard deviation, correlation, regression, random samples)
PDEs (I have no idea how to even approach these and the textbook complicates things)
Fourier Transforms
Double Integrals
d'Alembert's method
The paper is out of 120 and I need to get 48 marks to pass. I reckon I'm on about 20 with what I know from vector calculus, fourier series and simple probabilty. I basically fucked up because I spent too much time doing project work and not enough revising maths.
In the bigger picture I have 30 credits in the bank already from excellent coursework marks and maths is the only module I am struggling with.
Please help! Any help is greatly appreciated and I will love you eternally :)

I don't think their is a magic way to get all this in your head that fast. Should have just studied up for it. But only suggestion I can come up with is just study your ass off, take the shit one at a time, make sure you KNOW one thing, then move on.

Get some aderall or if you cant a pack of cigarrettes and mow everything down.
I didnt go to physics class the last two months and I had to cram everything in three days.

Try MIT's online courses. I haven't tried any of the math ones, but the science ones are pretty good.

Just skim over the pdfs and exams and audio lectures, maybe that will help?

Try and get a Math tutor to help you cram? Give each equation you have to memorize a certain tune, so it'll come more naturally.

Freedom is not something that is feelingly given,its something that you must constantly fight for,and if you don't make an effort for your freedom you cant ask for freedom,you made your decision now pay the consequences.

Math tutors are terrible for cramming. Math tutors are for dumb people that cant understand their math textbooks. its much faster to read through the textbook.

I think otomon has the philosophy behind the situation down

On the other hand, Winnie Cooper was a math tutor at University (http://i21.photobucket.com/albums/b291/ichigofrost/danica-mckellarx-large.jpg). She even has a mathematical theorem named after her.
Also I'm pretty sure the only things I understand in your original post is advanced probability. The rest is crazy moonspeak. I guess what I'm trying to say is you might aughta pop some adderall and get crackin'

I wish I was her derivative so I could lie tangent to her curves.

I think that was the worst post in GW history man...

You've got a very formidable list of crap to cram (meaning I don't know what half those things are) so I suppose I'll just suggest a few generally common-sense things to do.
First off, try to guess at what sort of problems will be on the exam. You can sort of gauge this from the nature of the problems that your prof gives you for quizzes, previous tests, etc.
By now and then, for each subject you need to read the textbook unit 8 times. Yes, 8 times -- thoroughly. Do a particularly hard problem after every other reading. You should improve. Maybe you can be absent tomorrow and tuesday so you can work on this stuff more? At any rate, after doing this for 2 units that you know will be huge parts of the exam, you should definitely be able to get more points.
Also, SLEEP.

I have learnt more maths this morning than I have all year.
I am on fucking FIRE.
I go to battle tomorrow morning and I am not going down without a fight. Pray for me, GW.

Double integrals are pretty simple, you just treat them like 2 integrals. Do the the interior one first, treating the other variable as if it's a constant, the do the outer integral.
e.g.
int(from x=0 to x=1) int(from y=0 to y=1) y(x^2) dy dx
would work out like
int(from x = 0 to x = 1) (0.5*y^2 x^2) dx
int(from x = 0 to x = 1) (0.5*1* x^2) - ( 0.5*0*x^2) dx
int(from x = 0 to x = 1) 0.5*x^2 dx
= (0.5/3)
(sorry for the crappy description, it's not easy writing maths on a comp (without Latex).
For fourier transforms, I'd make sure to know the matrix forms of the discrete fourier transform (DFT) and the inverse DFT. For these, computing the transforms of a vector (signal) is a simple matrix multiplication. Dunno if you'll need to know about the Fast Fourier Transform or not, depends on your syllabus I guess. Wikipedia all the way for a quick reference on things.
PDEs are a wide subject, which I was taught very poorly, so I'm not much help there. (What's your syllabus like/ Do you have to know about fiite difference methods, finite element methods, etc)
Can't help you with stats, I avoid them like the plague, not my field of expertise lol.

It's been too long for me to remember all the Advance Probability stuffs :S I'll just give you the website that I usually read up on when I need to do some quick study. Hope these help.
