Yea, you should hit these pretty soon. The math series I'm taking does this first, to prepare for E&M, I guess.

What math are you taking?

Actually, I'm in this really interesting theoretical math series that starts from the very beginning (The axioms: commutativity, additive identities, etc) and proves everything up to linear algebra and multivariable calculus from there. It's a tiny bit behind subject wise, but you get a ton more understanding and mathematical thinking ability. This semester'll be mainly linear algebra. What subject would the line integral fit into?

Edit: It looks like no one got my Euler's identity joke before .

Line integrals come with multivariable calc. You'll learn Fubini's and Stroke's theorems along with that. I'm doing Linear Algebra this quarter as well, then onto Differential equations after. Did you end up doing any discrete math in your series?

EDIT: ololol, I missed the Euler's identity joke. I skimmed through it too fast to see the e^(i*pi)

^^^^

I didn't even see that before. I just skimmed over and thought it was keyboard smashing.

And Zackie El, I give up. I'm giving the "Summer brainfart" excuse on this one.

What's the answer? I did it several times and kept getting 21.07.

EDIT: I did get it! My I just can't read my own writing. My ones look like sevens.

Yay Math!!!!!!!11!11-e^(i*pi)!!

I did it the same way as bigwillie and got 21.07 square units. Same answer, just different ways of getting there. I did a LOT of trig last year so that's the first thing I thought of.

^ I completely forgot about that formula. I remember seeing once or twice, but I never really went over to thoroughly.

I'm going to be logging off pretty soon, but I'll welcome any future problems. It will definitely help get me warmed up before I have to go back to school.

Should I quit doing problems, or keep going?

A fair amount, yeah. We used logical quantifiers all of the time in proofs, and we learned weak and strong induction. The series is almost completely focused on proofs, so you're gonna need some discrete. I'm going to be studying discrete on my own this semester though, because I need it for computer science, and I don't feel like actually taking the class . I'll just be taking the final so I can officially take classes that require it as a prerequisite.

#51

I took discrete math for CS and I ended up getting a C- in the class, barely passing it. That's because I don't give a sh*t about discrete math and I didn't study it. I get the material though. Again, ololol, I think we're doing the same exact thing in college.

#52

Physics/CS double major?

#53

Physics/CS double major?

I'm doing Electrical Engineering/CS double major. Close enough though, because I'm gonna be taking a buttload of physics classes too. I <3 physics.

Maths!

Wow I kinda didn't expect this thread to really get anywhere! lol

it's good to see there are people on UG who actually have a brain in their skull that's used for more than barrel rolls and icyhot...

guys..... i'm impressed!

I'm taking Specialist Mathematics (top maths subject in Australia), Physics, and Chemistry in my final year of school, so I hope I can be of some help...

but it looks like some of you guys are smarter than me.... so i might have to resort to coming back to my own thread for help!!!1

you guys talking about multivariate calculus and linear algebra- what age are you? I always assume people on here are of school age, but I studied that stuff last year at uni. I guess you're all at uni/college?

How do you find vertical asymptotes with just looking at the equation? Assuming the equation has one of course.

Gah.... Making The Science Thread Obsolete are we threadstarter? (see sig)

A challenge

What are the last 10 digits of:

Legion's number of the first kind 666^666

Legion's number of the second kind 666!^666!

With some kind of proof (don't just google it...)

#67

Basically, if it comes down to division by zero, that means there's a vertical asymptote.

Oops. Sorry, I meant horizontal.

To reper1234567: Do you know how to do it? Theres a way with modular arithmetic, which involves finding the remainder upon division by 10,000,000,000- but i cant remember how to do it and it wouldn't be much easier than just plain doing the sum.

To abcdboy: Horizontal asymptotes (which may or may not actually be horizontal), remember are the limits of your function as x approaches plus or minus infinity. These limits give you your asymptotic lines

Hey, Guitardude19. I'm expecting you to help me with my AP Chemistry because my teacher tends to ramble on about things that have nothing to do with the topic at hand.

Lol ask nicely

Nah its cool, PM me or ask the questions in this thread or the science thread. Im subscribed to both so yea...

Haha, sorry

Nah, I really appreciate it though. We're just doing review stuff right now, but I'm afraid once we actually get into things that he's not gonna teach us a lot (he worked with NASA and he tends to veer off into things about space) and when we get his test, expect us to know it somehow. I'm waaaay better at physics than I am Chemistry, even though they intertwine a lot. Thank you, though.

Its cool dude, as I said, your welcome to contact me anytime.

Ive had teachers like that, and Ive dropped their classes and just gone to another teacher of the same subjects classes instead... Not that the school was happy about it, but I was getting the grades so they let me do it...

Oh and I almost failed my Physics A Level because of it but Im not too good with math so that could of been one of the reasons as well...
