There's a difference between taking happy pills and being actually insane and a lot of people here regularly cross that line.

What is so hard to understand about soft bread being greater than rubbery sponges?
09-08-2014 , 11:52 PM
At one time I was able to type about 100wpm but I'm prob closer to 85wpm now.

Back when I was in school my math work looked at lot like yours. I had a few teachers that would get mad but I told them to get over it and just worry about the final answer.

Maybe you know about Ethiopian food? Butnah

I know about Ethiopian food. Just never liked the crappy bread.

It is a common complaint.

Many years ago I was a TA for an elective class with reputation for being really tough. There was this really smart guy in the class who was a complete mess when writing. Way worse than the notes you posted, I could follow those.

The exams were hand written and when I got to grading his I flunked him because I didn't understand **** of how he explained the solutions to the problems. He complained to me and the professor of the class but he sided with me. There were like four tests and by the fourth he was actually explaining stuff more clearly and he passed the class.

Here's hoping that you don't get an ******* TA like myself.

Hey, I did say that his writing was way worse than yours. There's hope.

"as epsilon gets smaller....I get it" seems like hand waving to me.

What it means for the limit 1/x = 0 as x -> inf is that for any epsilon (e) (any real number you can think of) there exists some value for x, say N, such that all f(x) or 1/x where x > N, |f(x)| < epsilon.

How can you prove that?

This only has to be true as x -> inf, so we're free to start with x > 0 and, thus x, N, and P (comes in later) are always positive.

Well, say it's not true. So, 1/N = e

and there exists some number P where P > N, but 1/P > e.

1/N - 1/P = e - 1/P
1/N - 1/P < 0, because 1/P > e
(P-N)/NP < 0
(P-N) < 0, multiply by NP, which is positive

This is not true, because P > N.

Contradiction, so our supposition was false

Therefore whenever x > N, 1/x < e


("what it means" is not exactly accurate, but that being true is sufficient. The definition of the limit is that every sequence in that set will converge to 0, and if every value converges then obviously (imo) every sequence does. - that's not the same as saying it's the definition) (And, I haven't really done math for 22 years, so I could definitely be making a mistake.)

that was one of my 1/100 posts that wasn't sarcasm laden

too drunk to respond right now but pretty sure you're wrong

I assume you're being sarcastic here.

One time this math professor was doing a very involved proof in front of the class. On moving from one step to the next he said, "so obviously that is true". After saying that he stopped and thought to himself, and then started writing in his notebook, erasing and writing and thinking for about 20 minutes while the class waited. Then he looked up and exitedly said, "yes, it was obvious!"

Such a tease. Now I have to wait until you sober up and respond and then I have to get too drunk to reply to that.
09-09-2014 , 12:38 AM
I didnt understand even half of that so i may just concede
09-09-2014 , 12:51 AM
Epsilon delta proofs are so goddamn annoying. You do like 10 proofs and they're all the same process but they take forever to write the same **** over and over again.
09-09-2014 , 12:52 AM
I'm really not trying to win. Trying to be helpful. It's probably not the thrust of your class anyway and you'll probably quickly move into solving problems. (finding derivatives, integrating, etc)
09-09-2014 , 02:36 AM
hahaha I do not remember any of that ****

Thank god, I dont know the guy very well but that NVG thread broke my heart and I didn't expect it to turn out very positive.

My brother has less of the brain induced crazy 'Iwannajump' but is way more sensitive to this, he fears being pushed in front of a train when standing on the platform. I dont have this too much as Im already scurred enough that Ill push myself.

I totally agree, ****ing about with knives and what not just seems very sub optimal when you can make such a great thing out of it. Nobody ITT (as far as I got) is really wanting to kill them selfs tho, its just some kind of reflex that your brain has.

I really wish I put some more effort into school when I was in it. This whole math stuff is making me miss it a little bit. Good old times.

What was your major? If it was science or engineering you probably did one or two of those in Calc 1A and moved on. In math that was (for me anyway) that was in real analysis. (104 iirc)

I have a mostly unused BSME lying around somewhere. Near-mint condition. IIRC (and I probably don't) I took math 1a,1b, 50a, 50b...so like two calculus, linear algebra and diff eq? Damn, might as well have been Swahili

I did have a Dr Wu like the steely dan song

I started out ME. Dropped out for a year, came back and switched to Math.

Engineering was too practical for 20 year old me.
