Least Favorite Mathmatecal Formula

[GruntOwner]

Anything from statistics.

Also, not so much a formula as a method, but there's sort of a formula to differentiation, so I'm gonna say integrating/differentiating the trigonomic functions... ESPECIALLY when you bring logorithms into the fray as well.

I loath math on the whole ... this is my MOST favorite equation though because there is truth behind it

You cannot deny the truth xD

Wrong, sir. Women require time AND money, therefore they are 2M. Mathmatically speaking, women would be the root of 2M, therefore a means by which you could double your wealth. As you can clearly see, women are simply too damn illogical to be applies mathmatically.

Standard Deviation, The teach you it wrong in GCSE then A level they go: "whoops sorry you take one off" I keep forgetting.

 

[randomsix]

I can never keep the integrations of Arc trigonometric functions straight.

 

[Maze1125]

No, I meant you proved me right in saying ti doesn't make sense.

But it makes perfect sense.
It only doesn't make sense if you think of decimals as something they're not.

Also, in your first post, you said that maths wasn't logical, not that it didn't make sense. Those are two completely different claims.

 

[Azraellod]

wow... numbers aren't popular here.

i'll go with the solution algorithm to ax[sup]2[/sup] + bx + c = 0.

because it's one that i can never remember.

Bessel functions.

where alpha is any arbitary real or complex number.

Useful in solving problems in cylindrical co-ordinate system. But I absolutely detest integral calculus beyond the extreme basics taught at college A-level maths (at least in Finland)

You just melted my brain.

I wish my head could wrap itself around these kinds of things. Alas, all I can do is art stuff. Algebra 1,2, Geometry and a couple of C programming classes is as much as my head can handle. The rest is dedicated to drawing, d&d, reading and film.

 

[SnowCold]

Algebra, all of it.

On second though, math as a whole.

 

[Sayvara]

Statistics... especially stochastic variables. There's somethign very hinky about a variable that does not have a value but rather a friggin distribution!!!

QUOTIENT RULE

dy/dx= (f'(x)g(x)-f(x)g'(x))/{g(x)}^2

I don't mean to be blunt here, but what the hell type of question is that?

I suppose e=mc squared. Not because I don't understand it but just because I cannot possible comprehend the vastness of the forces involved in it with my puny brain.

That's not maths, that's physics. I hate the Cosine rule [http://en.wikipedia.org/wiki/Cosine_rule] because it's a ***** to remember. I can rember the Quadratic formula [http://en.wikipedia.org/wiki/Quadratic_formula#Quadratic_formula] easier than that.

Edit: Oh, I also hate this ***** [http://en.wikipedia.org/wiki/Spearman%27s_rank_correlation_coefficient] aswell.

You learn about it in Physics but it's still a mathematical formula. Maths and the sciences overlap an awful lot in case you haven't noticed.

So because you don't learn a mathematical formula in mathematics, you assume that it isn't maths? newsflash, about 90% of physics if not more is applied mathematics. Mathematics is science in its purest form.

Well yeah, I knew that since I'm doing Maths and Mechanics as a course in college, but I've just never studied it in Maths.

Man+Woman-Condom=The Babies. God I hate that one.

 

[AlexFromOmaha]

Sequence alignment scores, or just about anything derived from PAM matrices, make me sadface. I have nothing but respect for physicists, who pull out much more insane stuff from much more insane formulas, like the above-mentioned Navier-Stokes formulas.

 

[Lunar Shadow]

Pretty much anything having to do with exponential and hyperbolic functions. They're just not intuitive (at least not to me).

At least trig formulas make sense, and they're easy to remember. Didn't any of you learn SOH-CAH-TOA?

Some old hag came around here tripping on acid, loved that mnemonic.

Stoichiometry, that is all.

Bessel functions.

This, and even though it is basic, the quadratic equation. I ALWAYS forget a negative and I don't know why.

 

[Nimbus]

Anything with the number i. Grrr.

 

[FoolKiller]

whenever something is only explainable via einstein notations it gets a little bit complicated. Navier Stokes equations of flow are pretty difficult. Can work with them vaguely at 2D level, but 3D is too complicated for me (and almost anyone alive, including computational models) to deal with

http://en.wikipedia.org/wiki/Navier%E2%80%93Stokes_equations

For those that have no idea what they are.

Hehe, I'm guessing someone will one up me with M-Theory now!

I love them to death... of course I went to school for aerospace engineering

 

[Heart of Darkness]

Simple interest, compund interest, and American-style geometric proofs.

Prove that this is a square.
American way: Three of it's angles are right angles due to the (_______) theorem. Three of it's sides are equal due to the (______) theorem. Hence, it's a square.

British way: All of its sides are of equal length and meet at right angles. A square. (At least, that's how I got it from my British math teacher...)
