Infinity. Ahh. Saying infinity is a number, which it is not, it is very likely that infinity equals negative infinity. This can be proven (?) by this proof.
∞ = 1/0 | Given (?)
1/0 = 1/0 *-1/-1 | Identity property
1/0 = -1/0 | Simplify
1/0 = -1 * 1/0 | Factor
That is assuming that ∞ = 1/0.
Also, the fact that a graph touches an assymptote at both ∞ and -∞ suggests that thy are equal, because the graph is considered a function.
Infinity and negative infinity are equal. The number line is circular.
It is difficult for the finite mind to comprehend infinity. The square root of infinity is negative infinity and infinity. To truly comprehend infinity, the number line must be a circle. Which means that negative infinity must be equal to infinity. Infinity is the zero of unreal numbers. -0=0 because -1 x 0=0. If we can't define infinity, we cannot define nothingness. So the definition of infinity must be a circle. The number line is circular.
But what I think is more cool is to prove pi with a calculater but without other external help, e.g. you can't look up an article about pi. For the arragant geek bragging record, I'm proud to say that I accomplished this soon after I learned what sines and cosines and stuff are.
Since this thread has forgotten it's roots, I'll raise another question:
Why can calculators justify that 1 / 3 = 0.3333333 x 3 = 0.9999999
