I've also found how you(ShamusHand) have come to ur soln...
continuing from my prev post
Say u want to find a number that gives the same result when divided by x and when x is subtracted from that...

Let, the number be y

then 

y/x=y-x
=> y=xy-x^2
=> y(1-x)=-x^2
=> y=(x^2)/(x-1) -----------(1) where x != 1

Got it????

Means if u want to find a number for which [that number]/6=[that number] -6 the just replace the values in equation (1)
i.e. y=36/5=7.2

if y=(x^2)/(x-1) then
u can write it as follows
y=(x^2-1+1)/(x-1)
=> y=(x^2-1)/(x-1)+1/(x-1)
=> y=(x+1) + 1/(x-1)

this is the soln u have got... right??? enjoy math.......

Nah, don't. It's your formula, but simplified. It's like a computer program, that can be made smaller and simpler by optimizing its size with different types of commands. It's like, if you have x + y = 10 + y, then you can remove that y and make it easier.

I suppose your right... But no Shamus' Theorem... :P

ok, I will try to think of it...
I graphed it...

and it looks like two parabolas, it's not a function too.
And the parabola avoids one.

Nice discovery, but the use of x and y just goes easy with it.

I don't know
Even if it was a theorm
Whats the use for it?

You never know... IT might get applied somewhere eventually. It might cure cancer!


I dont know, but it gave me a headache ;)

@zool It's funny that you registered here almost three years ago and an algebraic formula made your first post! :P

theim, i got geometry and i dont get, i am falling with 48 i dont do homework either

Do your homework, seriously. I do mine, but in Study Hall, Lunch, or Homeroom. Geometry was hard as hell for me too. Algebra I get, kinda. I still like basic math more than anything. :D



You want some fun math?


Play with Laplace Transforms. Good times.

This is the most boring thread I have ever read through, im 100% serious.

Math = Fail

I hate math, 90% of math we learn is useless in a real life environment.

LOL....




What seems useless, is not. Algebra for example, is one of the most important math skills you can learn, because it applies to so many other types of math. Without math, there is no science. Without math and science, there is no technology, no medicine, no cars, no roads, no bridges, no banks, nothing.



So, let me fix that for ya.


endritt+Math=Fail.

I can respect people not liking it, thats pretty common. I am just saying that it is not useless.

Yeah I didn't say ALL of it was useless, I said most of it, seriously, I doubt i will ever need to use pythagorus theorm... ever.

Maybe you won't. Others will.

It is a very useful theorem. You will see it throughout geometry, trigonmetry, calculus, integral calculus, vector calculus, differential equations, and probably further than that.

Lol, in the UK we dont have that
We have ONE less called "Maths" (yeah we call it "maths" not "math")

Its just one lesson, and you do different things like every few days.

Irrelevent really. The point is, higher end math uses that theorem fairly regularly. Most of what you see as pointless is to prepare you to be able to perform more complicated computations.

What my point is that,

You don't actually NEED to know HOW to even use that theorm.
Like, say if I wan't to be a lawyer, when is that going to come up in my career?

The only career I can think that its useful in is a teacher.

Let me add a couple others for ya there.


Engineers.
Phsyicists.



3. Architects.
4. Surveyors.
5. Builders.
