Algebra, Calculus, Statistics, Trigonometry, and All Advanced Math Quiz Thread

Present problems from your hardest courses Astner. I won't know what to do for most of them, so make sure I can look them up and learn how to do them on google. Try and help people out if they aren't able to solve the problems others have already solved. Don't just solve it.

I might not participate much because I'm just a beginner. There is no limit to the level of math problem you're allowed to present in this thread. It's primarily educational.

Where is "I see everything in numbers" at? Is that like, in the South or something?

I'd hope neither of the 4 courses you named would be Astner's hardest course...

For instance, this was the first task we solved in a course called Stochastic Processes.

And here's the solution.

I doubt any of you could explain what's going on here.

It's me declaring that I have achieved an altered state of awareness, obviously falsely. Not a location, even the location bar offers a second title or a place to declare something.

That would be other Advanced Math, this is everything math. Just clarifying.

I don't think that's a good idea. I'd be surprised if there was someone here who could understand—let alone solve—basic problems from the courses I had three years ago.

You should present problems anyway, you never know who is hanging around here....

I desire the education you have, and I'm curious how your education took off, mine isn't and I don't see it taking off because I don't fully understand how it all works. You've stated one of your past jobs and dealing with some type of Matrix? I don't recall which thread that was from, but could you tell me how you got that job, and how you're getting jobs, obviously your education makes you qualified, but here in America I'm lost, even with a resume like yours I wouldn't know where to start?

I'd say you just got good grades and took whatever courses you felt like taking and walla! However, how do you find these science jobs just out of nowhere, I know that they are out there, but how do you just find one that's around? How do you sniff it out? There's nothing local here, do you just have money to throw away on moving to more proponent locations in Norway, jobs offers? Were you just contacted and told "You're smart, want this job?" out of no where?!?

Prominent locations in Sweden.*

Your avatar looks like a Norwegian douche, threw me off.

Dolos: Learn calculus, then you can move on to the more advanced math.

The only posters I've encountered that have studied maths are AbnormalButSane and maybe lord xyz, both of which had a lower standard on their education.

Frankly, I think I'd be wasting my and other posters' time by posting advanced math problems with notations and operators no one here has seen before.

Why? Because ten years from now I don't want to find myself sitting in front a conveyor belt putting together mechanical pieces and thinking back on how I wasted my education by being lazy.

About a year ago, I was lucky enough to find a company who designed lenses in need of people to solve Jones matrices in MATLAB. I introduced myself asked what they needed and it turned out that I qualified. So I sent in my resumé, and got in contact with the employer over the phone about a week later.

I did everything from home and each day's work took about three hours (most of it parts of bigger projects I'd return to), though I got payed for eight. I worked five days a week for two months and earned 52,000 SEK or 8,080 USD after tax as well as a bullet point on my resumé.

That said, I don't know how it's in the States, but here in Sweden there are a lot of companies that will hire any newly graduated engineer who's studied either Engineering Physics or Electrical Engineering that I'm familiar with.

One of my friends got an interview and soon thereafter work at SAAB (Swedish defense force) as a field engineer from just one call.

There's not much to it besides hard work. I studied the Natural Sciences program in high school, and Engineering Physics—the most mathematically advanced program in Sweden—after that, and now I'm working on my Master's Degree in Fundamental Physics which I'll get this summer.

Two times every year my university hosts an exhibition where representatives come to hire students with sufficient education over the winter and summer. This to fill in for the workers who go on vacation during this time, and to save money because they can get away with paying students less.

It's Urumi Kanzaki from the manga and anime Great Teacher Onizuka. She's Japanese, and technically half-American.

It's like I'm talking to someone living in a fantasy paradise I could never have.

You're no more than 24, have earned over 8,000 bucks and an astounding resumé; and I'm a 20 year-old living in my parents basement weightlifting to impress chicks that I'm not impressing.

America Vs Sweden everyone.

I ****ing hate America, to my knowledge back in the 1960s Americans were like Gods all the way until it became the year 1990, then we stopped funding what matters, we stopped caring about education, science, research and development. Now look at how miserably retarded our 20 years-old. But hey, at least I'm aware I'm a bum, change can start with that.

But no one here, especially not politicians, listen to their President when he knows best and says that economic success requires change. Well after the 1960s we were perfectly willing to change from techno-progressive to this lowly state of selfish conservative loathsome broke loneliness. Americans might as a well be gay with the way monogamy has gone, every relationship around me makes me sick, self-materialism, trophy boyfriend, trophy girlfriend, there's no romance here. No one cares about anyone anymore around here. Haven't seen much meaningful affection in my life between anyone except children and sometimes family; and it can't mean much between children. And families? pfft. We are such a pathetic generation.

We might as well be fascist, fascism that annotates being miserable and lazy.

We've fallen.

We are living in a self-centered society, with a falling interest in being productive, creative, and using that to address difficult problems with any positive mind-set, that to me indicates that it will not be much to speak of in 30 years. Certainly not the number 1 superpower.

I'd attribute my successes to hard work and a supportive family rather than to my country.

Isn't that how a capitalistic society works; the ones with the most money make the most money, and those without gets left behind?

Robber barons are gone, so not really. We get the same opportunities, we just have to show that we're cut out. We get benefits for showing academic aptitude reflected from a good GPA. It's still expensive, I don't consider unreasonable by any stretch of the imagination. Where as if you're rich and you have a horrible GPA, you're throwing away. That is reasonable.

That's not the problem, the problem is that there are too many bums who don't work hard and have dysfunctional families...like me.

The question is asking you to show that an expectation value of random X is less than or equal to the probability of the event of X greater than n. The permutation goes from 0 to infinity. Throw in some set theory and integral properties, sprinkle some algebra in, and then, bam, you show that the expected value is at the most equal to the desired proof.

We did this in highschool. Don't ask me to tell you about the proofing structure because it has been over a decade.

And it's not like I asked you to prove anything. I already did it. I just wanted an explanation of what methods I used and why, which you failed to provide.

Let's be honest. You searched Wikipedia for traces that could make you look smart. You found out what E and P stood for—which isn't hard considering they're two of the most commonly used functions in all of probability theory—you called it a day still failed to comprehend the initial expression. And you didn't even bother with the proof.

And this took you over four hours. (Yes, I dropped in every hour or so to see if you still lurked around.)

I on the other hand have the advantage of not only knowing this particular example, but also having passed this particular class with a five.

So if he wants to make a big deal of it I'll have to bring him down to earth.

We just saw how a foreigner's education stacks up against an American's.

Things aren't looking food for us, Barker.

And no I'm not unpatriotic. It would be unpatriotic to do what 99.99% of Americans are doing and ignore these tremendously foreboding warning signs. We're ****ed, some economists say there's no way we're not getting passed by at least a dozen other super powers in the very immediate future..

Out of thirty one participants our scores were #21st, we're not even in the top 20 Barker.
