Lol maths. Ever hear of grahams number?

Lets get a bigger number, by 500000 orders of magnitude

My contempt for you all is tangable :badass:

I can't believe I laughed at that.

Rimrook, n/0 is undefined, not infinity. The graph of n/x has a discontinuity at x=0.

QFT.

In other news, I just did a Maths Exam today.

So can anybody tell me what the answer is of:
(a?^-1 + b^-1)^-1
I think we had to simplify it,

^-1 means to the power of negative one

lol I thought everyone would go home (from school or otherwise) to relax, not start doing more problems -_-

But while Im here I mise well post a problem:

If csc? = .4534 then what is the angle? What quadrant is it in?

I think we had to simplify it,
1/(1/a+1/b)

and whatever that simplifies too, I forgot from there since I did algrebra so long ago, cant be arsed to remember.

That can't be simplified any further, can it?

There's no answer, .4534 doesn't fit into csc's range. The resulting value must be greater than or equal to 1, or less than or equal to -1.

Posted 12 years ago2007-06-14 11:07:09 UTC Post #225218
Stupid. It's pretty damn obvious why you can't devide by zero.

You fail as much as Jimmi did when he tried to convinse me this:
1 + 1 = 1.

He had a really looong and really stupid equation....
Posted 12 years ago2007-06-14 11:22:24 UTC Post #225219
Technicaly, one divided by zero equals infinity, because you have to add zero to itself an infinite amount of times until you reach one.
It's the same with two.
Infinity doesn't go by the same rules as normal numbers, as two different infinities could be either the same or different.
So Espens post is wrong.
About Cabooses equation-

9.999 - 0.9999 = 8.9991

8.999 / 9 = 0.9999

If by 0.999... he means that it goes on forever, then it has the same problem as Espens post- Infinity doesn't go by the same rules as normal numbers.

Small logic based challenge:
Take the hard or the easy one.

The goal is to find the values of x, y and z. The three have the same values on both difficulties.

y^2 means y to the power to 2

Hard:
xy^2 = 48

xyz = 84

xzy^2 = 336
Easy:
x + y^2 = 19

x + y + z = 14

x + y^2 + z = 26
Posted 12 years ago2007-06-15 07:00:15 UTC Post #225289
hard
x=3
y=4
z=7

easy
x=10
y=-3
z=7

not really a logic based challenge, since its just a regular substitution question. also all three dont have the same values in both questions

Wow seriously what math did you come from people? Go back to second grade. You cannot divide by zero, it is undefined! You just can't do it. It's not infinity, it's not 0, it's a "0" with a lin through it. Got it? good.

Also, I'm surprised you all debated espen's equation for so long, being as the only problem he was having was basic order of operations...oh yeah and simple knowledge of NOT DIVIDING BY ZERO
Posted 12 years ago2007-06-15 07:13:36 UTC Post #225291
i just discovered that the 'easy' problem has 2 answers. be careful next time you make this stuff up, espen.

also, are you still going on about dividing by zero? listen to vox if you cant read what i said on the last page.

also, learn to maths TJB

a=0.99999........(RECURRING TO INFINITY)
10a=9.99999........(RECURRING TO INFINITY)
10a-a=9.99999........(RECURRING)-0.99999........(RECURRING)
9a=9
a=1

this is a PROVEN MATHEMATICAL CONCEPT. ANY RECURRING NUMBER CAN BE RATIONALIZED THIS WAY. FOR EXAMPLE:

x=0.146146146146146....(recurring)...note that recurring digits are 146

1000x=146.146146...(recurring)
1000x-x=99x=146
x=146/999

try it. type 146/999 into a calculator.

0.99999...recurring to infinity = 1.

in summary

you ABSOLUTELY NO WAY IN HELL can (no really, NEVER EVER EVER) divide ANYTHING AT ALL by zero.
NOTHING. x/0 where x is an element of I or R or 0 or anything is UNDEFINED. 1!=2. end of story. seriously.

and

0.9999999999.....(RECURRING TO INFINITY. IN-FUCKING-FINITY) = 1. there are no mathematical arguments. none. it is not disputed. it is correct.
0.9999999...recurring = 3*0.3333333....recurring
0.333333333333...recurring = 1/3
3*1/3 = 1
EQUALS ONE.

NOW SHUT THE FUCK UP.

Actually, if you use correct mathematical notation, 1!=2 is incorrect. 1!=1x1=1. :biggrin:

Posted 12 years ago2007-06-15 18:34:24 UTC Post #225357
easy
x=10
y=-3
z=7
That's another solution, but I'll show you that I was also correct:

Here's your answer:
x + y^2 = 19

x + y + z = 14

x + y^2 + z = 26
Now let's convert that into numbers:
10 + -3^2 = 19

10 + -3 + 7 = 14

10 + -3^2 + 7 = 26
Here's mine:
3 + 4^2 = 19

3 + 4 + 7 = 14

3 + 4^2 + 7 = 26
So you can't say the values aren't the same, but you can say that the values are the same, but the easy version has another possible solution, as Penguinboy stated earlier.

Expand: (a+b)

(.a.+.b.)
(..a..+..b..)
(...a...+...b...)
(....a....+....b....)

As you can see, I'm great at maths.

EDIT: DAMN SPACE FIXING.
