Journal FortKnox's Journal: Integration-By-Parts Man! 21
Heh, my old roommate used to refer to me as "Integration-by-parts man" because I was really good at integration by parts. Last time I used integration by parts was calc III (maybe calc II). I don't think I ever needed complex enough integration in any of my core classes to require integration by parts.
One of my family friends is in college (my school, my degree with some influence by me) who is having trouble with it. Seeing that I took calc3 in the beginning of 1996, I'm a little nervous about teaching (let alone seeing if I remember it well enough to work the problems myself). I don't have my calc book anymore, so it looks like I'll have to peruse the web to a page that has a little explanation to jog the 'ol noggin and maybe some problems I can work through. I don't suppose anyone knows a site like that (I really do not want to pay $100 for a calc book, if at all necessary).

And No. I don't know of any resources. Might try going to Barnes and Noble- they might have a tutorial that you can peruse in the store.

I actually used it once... (Score:2)
I got to use it once, about a year out of college, when I worked for a digital signal processing group and we wanted to check something manually to see if it was approx. the expected result.

Book price (Score:2)
So don't. I know that text books are expensive in the US, but they don't have to be that expensive. Anyway, the book you're looking for is "Engineering Mathematics" (or possibly "Advanced Engineering Mathematics", check the contents of both), by K.A. Stroud. Amazon US have it for US$60. It's cheaper from Amazon UK, although check the shipping price (I can ship it for you if necessary).

Calc III unlike the previous two classes, was kind of fun. I mean... You get to deal with vectors, and fun visual stuff and math in 3D.

Hooray for the cross product! Hooray for the Del operator! Hooray for Maxwell!

But I switched to computers to avoid the evil Organic chemistry class. Well that and I kept getting summer jobs in computers instead of chemistry so I eventually took the hint.

Calculus is the mathematics of change. Just remember that you too, are a vector. Now get your vector ass back to work or I'll integrate you by parts!

Beautiful Integrals (Score:2)
How to find it is sheer beauty...
Let I=Integral {e^-(x^2)}dx, then I^2=[Integral {e^-(x^2)}dx]*[Integral {e^-(y^2)}dy]
Since x and y are independent variables, I^2=Integral Integral {{[e^-(x^2)]*[e^-(y^2)]}}dxdy
so I^2=Integral Integral {{e^-[(x^2)+(y^2)]}}dxdy
I hope that my fellow mathematicians will allow me to skate over the rigour here (as I'm a little^H^H^H^H^H^H^H^Hvery rusty) whilst I invoke geometrical intuition with a flourish
Calculus? I did that at A-levels (Sixth Form) (Score:2)
Ditto for Statistic. Know the principles, buggered if I can remember how to apply it.
But Logic? Yeah, I know Logic? Every which way. God help me!
