too bad infinity is not a number
Infinity is not a real number but may be considered part of the extended real number line, in which arithmetic operations involving infinity may be performed.
You're right, infinity is not a number. But use INFINITY in Calculus to find ABSOLUTES!
The point is that you can't count to infinity, because no matter how fast you count, you will be counting forever and ever
In calculus you don't "use" infinity, when you find a limit for example you define some number that approaches infinity, but isn't "infinity".

Well Chuck Norris did. And then did it again.

He must be counting to infinity infinitely fast. Then this is interesting

toxic, a question for you
0 x infinity = what ?

Infinity's new definition from this point forward: The number of times ToxicBug would post a retarded statement if he were to live forever.
No value in the physical universe can ever reach this limit, only approach it.

I've got a calculus problem for you, TB.
Try solving for '
m' on the curve of knowledge you've gained since you started University, at points [1,0] [2,0] [3,0] and [4,0].
Notice anything amiss?

its an indeterminant form. just like 1^infinity, 0/0 and infinity/infinity. If you take a limit as x
infinity then it will depend on the example. A good example of 0/0 (ie 0*inf depending how you write it) would be the limit of sin(x)/x as x
0.

Trust me, you don't have to tell me that. I'm obviously refering to limits, euler sums, and integrals.

By the way, if you would like to know the limit of sin(x)/x as x
0, you can find it by using L'Hopital's rule, ie when the limit f(x)/g(x) is in a 0/0 or inf/inf form, it equals to f'(x)/g'(x).
f'(x) = d/dx sin(x) = cos(x)
g'(x) = d/dx x = 1
Therefore the limit of sin(x)/x as x
0
= lim x->0 cos(x)/1
= cos(0)/1
= 1/1
= 1
So the limit of sin(x)/x as x
0 is 1.
