### Re: function machine

In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is where

The letters a, b, and c are called coefficients: the quadratic coefficient a is the coefficient of x2, the linear coefficient b is the coefficient of x, and c is the constant coefficient, also called the free term.

[Edit: too long (!!!), and it's all on Wikipedia anyway. ~justlooking]

as you all know i have no idea what  ≠ is and no ida what tons of the other sutff means. i have copied and pasted it so everyone doesnt have to go offline to read it and tell me what those complicated words mean

### Re: function machine

Could you be thinking of the equation of a straight line?

I think that's the notation in England atleast. If you're not from England, it might look different.

Devanté - That's why I said

Yup, as far as I'm aware you probably havn't covered this topic yet, though

But to be honest, I have a very limited knowledge of school systems in other countries.

Deja vu can also be partially simplified to nostalgia.

### Re: function machine

It's kind of the other way around.

Nostalgia is you remembering stuff that happened ages ago and getting a warm fuzzy feeling about all of your happy memories.

Deja vú is you seeing something happening in exactly the same way to the way that you saw it happening before some time ago, which is unsettling because in this world of chaos and unpredictability that doesn't happen very often. Obviously, watching videos and stuff that will obviously always be the same doesn't count.

Why did the vector cross the road?
It wanted to be normal.

### Re: function machine

yep its deja vu definately lol. this might sound weird but ive been having weird dreams lol and then it either happened the next day or in months or even years. one example is when i was like 7 years old when i played ff7 i dreamed of a new ff7 and it was covered in red and it said dirge of ceberas. now 5 years later theres a ff7 dirge of ceberous lol. note: ff7 advantchild was so good. but cloud should of suffered more and aeris should of had more parts

### Re: function machine

if im not mistaken you get a deja vu because your eyes accidently sends two signals to the brain so when the second signal reaches the brain you think you have seen it before...or something like that
