What's your favorite math subject? and your least favorite?

I'm taking a re-exam for one of my math classes (4th time I do this shit), and it's some basic billiondimensional stuff, you know the kind. Anyway, I love the lagrange multiplier stuff, and the stuff that can be expressed equally as an analisys problam as well as a linear algebra problem. But those fucking integrals!
It's just so fucking tedious. We're even allowed to use maple for the full duration of the exam, and still; Bweeurg!

But discrete maths, that's fucking delightful! Galois fields and stuff, waw! Also, probability theory has some really cool proofs and results, too bad I only have 2 classes on it.

Favourite thing I've been taught in math courses would likely be probabilites.
3D geometry in game design was fun too. Maybe the most interesting (and most 'mathy') stuff was in modelling parallel programs with composed state machines.

Sup guys. I'm a couple weeks into my first MATH class that is based around proofs and it turns out I'm fucking awesome at this type of thing. I had a very difficult time learning Cal2 and Cal3 because of poor quality of previous education, other factors, etc.

So, my question to you guys is, what do the people that are naturals when it comes to the formal proof methodology of thinking do? What kind of career should I be focused on, and what are other classes that are similar to this type of thing? I know it will depend on university wrt names of classes, but I have heard Modern Algebra is one of them and Real Analysis is another.

I'm also interested in "Set Theory", but do not know where to start or if/how it relates to proofs.. Thanks.

I look at math equations and I read aloud what pertains to the universe (1 and or/2 [in the future which is the past])

I just write out simple math equations


1+1 = life, 2=life with god, 2+2 = universal communication. and there are many more outcomes, simply one for each individual for those simple equations.

Its like I can peer into the soul of other people with math.

Lately, my math equation of my life = 2+2=5 (1 being innate, the universe) waiting for it to become 2+2=6. (when 1+1 (FOR HOW DOES ONE BECOME TWO WITHOUT BEING ONE ITSELF) becomes the new innate and we shift into the next predestination by means of a new god)

More info on 2+2=5 is I died, saw the universe, deemed everythings plural, thus attempting to recreate my lifes equation into 2+2=6.

The hyperreals fill in the gaps between the meanings we can express and the ones we can't. Everything is continuous, but our finite minds can only approximate with the discrete. While we're in 2+2=4 our experiences will point outside of it, leading to the intuition that infinite small quantities exist wedged within the cracks of our existence. It is just as true but we cannot touch it without transcending to beyond 6, into an inaccessible singular quantum that cannot be even expressed in this frame. From the regular reals, we add all these quantums to get the hyperreals.

Essentially they're between the kinks. x-19y = 404z^2/9

One thing I want to work on is these box construction problems.
A box is being constructed by cutting 2 inch squares from the corners of a rectangular sheet of metal that is six inches longer than it is wide. If the box is to have a volume of 270 cubic inches, find the dimensions of the metal sheet.
L = W+6
H = 2
Does the volume, 270 = (w-4)(w+2)2 ???
How do i set this up? is that right? would appreciate as much help as you can give. Thanks!

Skip trig if you want, but make sure you're a god at trig.
If you have a good calculus teacher, s/he'll make you practice trig inside and out.

It also depends on what you're wanting to do.
If you're a math or engineering major, then you'll want to formally introduce yourself to the basics by taking trig.

I never took trig nor precalc - in highschool or college. Hell, I just skipped my last two years of highschool. I took a placement test and was allowed to go straight into calculus. What little trig I needed to know for calculus was in an appendix at the back of my calculus book. I was taught the basics of trig in geometry anyway; and I taught myself the derivations of the identities I wasn't familiar with. IMO, devoting your time to an entire course in trig is a waste.

I'll spare you the details and tell you my basic situation. I'm a 2nd year college student at a community college and in order to graduate in a timely manner I need to take Pre-Calculus. Problem is I don't have the math requirements to do it, so I need to re-take a placement test in order to get a good enough grade to take it.

I have a couple study guides with example questions and such so there's basic arithmetic (addition, decimals, fractions, etc.) and things like rational numbers, polynomials, quadratics, scientific notation, factoring (honestly I could probably scan the study guide if someone really wanted me to).

I was curious if anyone had any specific studying advice or really anything remotely useful because I'm freaking out about this because this shit is pretty goddamn important.

One thing I remember is you have to know a^2 + b^2 = C^2

that's all i can remember.
that and know how to solve for x, know how to factor.

And there isn't like a letter grade it's just like a score. I have no idea how it works but I know need to get like over a 31 or something.

If you define an inverse operation as (in addition notation):
a + b = a + (-b), then the inverse operation is never commutative
(a - b does not equal b - a)
regardless of the status of the original operator unless both of those elements are identical.
I smoked nicotine, cannabis, drank coffee and went for a walk while listening to Terence Mckenna and this literally fell out of my head. Is this right? If you wrote the inverses of the inverse operation expressions, they're different unless the elements are identical, in which case it returns the identity element. You guys ever realize really specific shit like this while out and about?

If you used the multiplicative notation, this result would appear far more intuitive.

a/b = b/a if and only if a = b.

I love getting those realizations out of the blue. It's even better when I'm intoxicated.

This is false. Consider that a/b=b/a is true as long as a^2=b^2. So if we let a=-1 and b=1 then our statement is true but a and b are not equal.

I'm sure you can think of more examples.

So, I have a math placement exam coming up, and I am pretty sure I am fucked.
Though I did well in math during high school, it has been a few years since I graduated, and none of this is looking too familiar.
I am particularly having issues with finding domains. I have been trying to find practice problems similar to the ones I am working on now, but to no avail. I have an answer key to this practice test, but it doesn't explain shit. So, if someone could please explain domains in plain English, that would be great.

Here are some of the problems that appear on the practice test. I have simplified them, but I just don't understand at what point I am supposed to be finding the domain (before or after simplifying) and how to do that.


Basically, I feel like a fucking idiot, so if anyone could help, I would be eternally grateful.

What I'm wondering is, what would it look like when a higher dimensional being moved through our dimensions? Obviously not a completely serious thread.
The artist/scientific portion of what I'm asking is: What would an intelligent life form look like in their n-dimensional glory?
The mathematical portion: I know you savages are capable of projecting n-dimensional structures into 3-dimensions. Has anything cool like this been done before? I'd be much more interested in projections with a time dimension.

The reason this interests me is that I'm fascinated with absolutely massive structures. The idea of a rapidly transforming organic structure popping in and out of existence is probably the most epic thing I can think of. The Halo games have been the most impressive things I've seen when it comes to showing you things with breathtaking scale. If the n-dimensional organic being was huge and a special effects company or game developer decided to take a swing at something like this, I'd be thrilled. I wouldn't mind you guys just talking about this instead of linking to media. I just don't hear this talked about very often.

That's exactly where I got the idea, actually. I was just wondering if you guys could get crazy on me. As a physics student, we regard you math guys as people who just do wild shit for no reason that nobody ever asks for. We pretty much assume that you could answer most questions we have but as I've framed my questions as more open, I don't expect too much. I will certainly be reading flat land and flatter land and hopefully smoke DMT at some point in the process. Right now both of my threads are the top threads.

I'm just repeating myself here, but read Diaspora. Flatland and its sequels are good but if you already have some math background they'll all cover some pretty obvious stuff.

There are tons of ways for life to exist in a world with three spacial dimensions, and even more in four or more, assuming physical laws which work in those spaces. Do you have any more specific questions or do you just want to be entertained?

If people in a four dinensional world had cars, their wheels could have two degrees of freedom and still be 'flat' on one side. Their roads would approxomate three dimensional tubes kr parallelpipeds and the wheels would touch the road as a flat 2d shape instead of a line. There would be no left or right side of the road, but the road would probably still just connect two points in something approximating a thin line as they do in our world. I could go on and on but after a point it's really pretty boring.
