Mathematics rant

[ktimekiller]

I have had problem with terms and keywords of mathematical components in ALL levels throughout my entire time in education.

If I have the equation and formula, I am perfectly fine and can solve it without a hitch with no difficulty and with great speed but for the death of me, I can NEVER EVERR!1one memorize different words and terms that come up during lessons, and I cant understand conceptual wordings unless its shown in numerical and symbolical fashion.

Cool story brosef.

 

[Naudian]

Yeah me too kind of a little.

 

[PriNcE oF SpAcE]

1+1= you suck.

 

[mindless_moder]

give us a "for instance" ...

 

[Insano]

0,99.. = 1

That's all you need to remember.

 

[Remus]

0,99.. = 1

That's all you need to remember.

0,99.. = 0,99..
1 = 1

:arms:

 

[Druckles]

0,99.. == 0,99..
1 == 1

[AKIRA]

here's a math question maybe someone can help me out with...let's say you have a matrix A:

4 8 2 9|b1
6 0 3 1|b2
0 0 0 0|b1-b2-b3

in order for there to be at least 1 solution...does b1-b2-b3 have to be 0??

In one of my notes that's what it says, but I was under the impression if the last row is all 0's then there are an infinite amount of solutions...and if it's all 0's but b1-b2-b3 is a number then there is no solution because 0 can't equal one..and exactly one solution for any other situation???

HALP

 

[DEATHMASTER]

0.99.. = 0.99..
1 = 1

fix't

I'm 100% exactly the same.

if you end up with
0 = K , K some constant .. then you have no solutions
if you have 0 = 0 and leading 1's in other variables then that means that no matter what value you have for that last variable you will always get a 0 because its coefficient is 0 so you can replace it with a parameter t and express the other variables in terms of it.

 

[Jintor]

Mandlebrot's in heaven

At least he will be when he's dead.

Right now he's still alive and teching math at Yale.

 

[Insano]

0,99.. = 0,99.. = 1 = 1

[Pi Mu Rho]

Pi = 3

 

[kineaesth]

Oh f*ck I almost raged at that Pi. But then I realised.

 

[MJ12]

**** math.

And I don't get the Pi joke, why are we not raging at him for getting it wrong?

 

[Pi Mu Rho]

Because I'm right, duh.

 

[kineaesth]

Yeah, sorry, let me clarify. I almost raged at Pi. But then I realised. I realised he was right.

Pi does equalsign three.

 

[Kyorisu]

0,99.. = 1

That's all you need to remember.

It's tending towards one and therefore is one for all intensive purposes. Get it right.

[Druckles]

x = 0.99999;
y = x;
y = 1;

Think what you will.

 

[Avoidist]

I think that's cheating.

2 + 2 := 5

HA!

 

[Druckles]

import logic

 

[DEATHMASTER]

x = 0.99999;
y = x;
y = 1;

Think what you will.

clearly, x + y must then = fish, its only logical by those standards.

 

[Azner]

Also 1+1 is window

[Druckles]

No, it's 1.99...

 

[DEATHMASTER]

I'm surprised you didn't say 2.

 

[Druckles]

That would be making the assumption that 0.99... is 1.

 

[Gemma]

:arms: ????
wut does that mean?

 

[VirusType2]

wut does that mean?

 

[Minister]

I freaking love Mathematics!!!

 

[mindless_moder]

if a^x = a^z
then x = z .


1^0 = 1^5
therefore 0 = 5

 

[Druckles]

Does that mean 9=0? Because I like 9.

 

[soulslicer]

****ing agreed.

 

[Adabiviak]

You're doing it wrong.

ktimekiller, I think the answer to your question is that you have a different style of learning; it's not something inherent with mathematics.

 

[Insano]

That would be making the assumption that 0.99... is 1.

Oh, man. You're serious?

x = 0,99..
10x = 9,99..
10x - x = 9,99.. - 0,99..
9x = 9
x = 1

I have a math degree (university) and 90% of the time all the terminology is a BS waste of time. So is "showing your work" & so is having to follow a specific step-by-step process that the teacher shows & so is tons of math homework as a teaching-method.

 

[Minister]

I know Maths is a load of old codswallop but I lurve it!!

But not as much as Mechanics. Materials on the other hand can go suck my fish.

 

[theotherguy]

I am taking Concepts of Mathematics at Carnegie Mellon University right now.

I have been told this is the hardest freshman math course in the country, and I believe it. The average grade on this upcoming test has historically been 41/100. I had no idea of what was going on for the first 3 weeks before I had to get tutoring, get a study group, and go to office hours.

The class is basically teaching proofs, combinations, induction, etc. Its more about having brilliant strokes of intuition than being able to do computation, though it certainly helps if you're extremely good at algebra.
