Wroooong. Both of you.
Well, you could do it darkstar's way, but that's too complicated. Last edited by Zackie EL : 08262007 at 01:08 AM.

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 . Last edited by guywithguitar : 08262007 at 01:08 AM.

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)

It's 21.07181307 units^2
Using Hero's formula which is The square root of s(sa)(sb)(sc), and you find s by doing s=1/2(a+b+c)

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.

Well, that is right. I didn't see your edit, so sorry Hero's formula is easier, though. I have to use it a lot being a machinist.

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.

Should I quit doing problems, or keep going?

^ 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. Last edited by bigwillie : 08262007 at 01:22 AM.

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.

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.

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.

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?

Meh, I'm 16. A junior in high school.

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

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