What do i do to become a math whiz?

[Anonymous No.5496147]

lots of math

[Anonymous No.5496160]

also a certain laziness

[Anonymous No.5496163]

>>5496160
so true

[Anonymous No.5496168]

>>5496163
like when Gauss' teacher asked all he pupils to add all numbers from 1 to 100 and Gauss solved the problem faster than anyone else by simply adding any number pair that sums up to 100, just because he was to lazy too add them all one after another.

[Anonymous No.5496172]

start by calling it mathematics or "maths" if you must contract it.

only idiots say math.

[Anonymous No.5496169]

>>5496160

I think I went a bit far with the "laziness" part.

[Anonymous No.5496179]

Not OP Here but math is seriously my weak suit. I'm on first year physics/chem but holy fuck i can't even graph functions, know the bare minimum of trigonometry and most of precalculus has fucking raped me.

The field im getting into requires an immense knowledge of math. How can I make this "weak suit" my "strong suit"? I'm willing to do anything and everything.

Are you sure it's really the field you want to get into?

Try to understand the concepts on a fundamental level.

i dont hate math. I just never really paid attention in it now im so far behind.

Yes. It is the field i want to get into. It's essentially theoretical physics.

All you have to do is pay attention and practice a little.

It's the most straight-forward kind of thinking it isn't to difficult.

study math an hour a day and in a year you'll be smarter then 99% of the people here. I hate the faggots who repost shit from Wikipedia, use Wolfram Alpha for solving equations and act like they're some kind of super genius

then why the fuck are you in calculus holy shit

[Anonymous No.5496250]

>>5496242
can you autists fucking read

im doing first year sciences/maths and getting raped. I am getting along okay in physics/chem first year but i am getting ass raped in calculus because i dont know fundamentals and am weak at math in general. i dont hate math i just didnt pay attention in highschool.

>hurr y do u want to get into theoretical physics
because i like theoretical physics

are yu retard

can anyone help me with this problem?

x^2 + 2x + 1 - a^2

x(x+2) + 1 - a^2 stuck here(not even sure if on right path)

tried switching a^2 and one and taking out a -1 to make -a^2 positive so i get a difference of 2 squares. didnt get the final answer

no it's not hw. just reviewing math for when i take precalc

[Anonymous No.5496260]

no It's because you're an idiot, 5 year old kids in South Korea do calculus

[Anonymous No.5496261]

>>5496250
calculus was invented to describe physics.

if you can't into calculus, you can't into physics, let alone theoretical physics.

You only ever need to know applied math. Pure math is a waste of life.

Either you're some kind of aspie savant or just talking out of your ass. Physics requires more math than a math major studies, and chemistry is not far behind.

[Anonymous No.5496418]

is that true or is it just a myth? anyways, it is still awesome.

[Anonymous No.5496429]

Really? What math does a physics major study?

Most commonly Calculus I through III, assuming the individual took Algebra I and II as well as precalculus or a precalculus equivalent in high school or passed their SAT with sufficiently high mathematics scores. Of course, this is just assuming they're going for an associate degree. Bachelors usually also requires courses in statistics, among other things, with more advanced mathematics later on.

Nowhere near what >>5496410 made me think then. Not more than a math major and certainly not even close to inmense.

[Anonymous No.5496458]

>>5496455
While physics does get into a lot of advanced mathematics, it's nowhere near as much as the average math major. However, as the amount is still rather substantial, I'd recommend opting to have mathematics as a minor since you'll be doing a lot of those classes anyway.

[Anonymous No.5496459]

>>5496455
>>5496449
Oh, much more than you could ever imagine. Especially in theoretical physics... new developments in TP ar ebasically inventing new math.

Up to linear algebra in first 2 years, and then pretty much everything else like partial differential equations, Fourier analysis, complex analysis, Riemannian geometry, More general geometry of principal and vector bundles: connection, curvature, etc. Spinor geometry
Lie groups and representation theory,deRham cohomology... all sorts of other shit no one's heard of

[Anonymous No.5496465]

>>5496147
this. Intelligence is also a factor, but you cannot get good at math without doing a lot.

The upshot is, it doesn't have to be any particular kind of math. Just study the math that is relevant to your interests.

[Anonymous No.5496466]

>>5496459

Nothing uncommon for math major though.
Also, I don't think theoretical physics is a good example, they are at the very extreme of physics and as far as I know it's so far from verifiable experiments than it's nothing similar to any other type of physics major.

All the upper division math you need will be covered in a math methods course. Pure math is worthless to someone who needs to get things done. These books teach you what you need.

Any math major who hasn't heard of every single one of those is not a math major. That stuff is standard curriculum, especially for applied mathematicians.
