I need your help on the Limits to Infinity page.
Any criticism would be good, but there is a section which may be downright wrong, but I have not been able to prove or disprove it. It is marked with warning signs around it, and reads:
if the Degree of the Equation is:
* greater than 0, the limit is infinity (or -infinity)
* less than 0, the limit is 0
And also, what do you think of these bold statements
* When you see "limit", think "approaching", or
* the limit is infinity (which is really saying the function is limitless).
You won't hurt my feelings, it is only a draft, so let fly!
I would agree with your proposition surrounded by warning signs.
Earlier, you defined the degree of a function as the limit of log(f(x))/log(x) as x goes to infinity.
log(x) goes to infinity as x goes to infinity, and so for the degree to be positive, log(f(x)) would have to go to infinity as well.
Similarly, for the degree to be negative, log(f(x)) would have to go to -∞, which means that f(x) would have to go to 1/∞, or 0.
The rest of the page looks really good as well. It might look a bit better if you could remove the white background from where you've been using LaTeX.
Why did the vector cross the road?
It wanted to be normal.
I fee that I may be right, but it only takes one exception to disprove it!
Plus there is always a risk when one tries to simplify. I won't feel happy publishing this page until it has been under the microscope for a while.
wow i didn't know ther was a mathsisfun advanced wow cool (i now feel paralysed ) my mind is blank :S

I seriously don't know. Basically infinity isn't actually a 'number' its just a term so its easier to move around, at least thats what I think. I don't really know but I'm going to go with ' not greater than 0 but not less than 0'.
