I saw this Reddit post today saying "My son's third-grade teacher taught my son that 1 divided by 0 is 0. I wrote her an email to tell her that it is not 0. ...
It breaks calculus, the math that made your phone and has a billion other uses. Directionality of infinities is critical. In calculus, infinity refers only to the magnitude of the resulting vector. Because I suspect you don’t know, integers are a 1-dimensional vector.
No but some of the values/specs were calculated by summing an infinite number of infinitely small values. Take a calculus class brother, it’s a cool subject if you’re interested in infinity
I kinda already did many, though. Do you honestly think I argue math from my own imagination? Not sure I can do that while remaining logical ánd finding exactly the same info online if I look it up, cause that would be kinda amazing.
You did many. Well, yeah, I honestly don’t believe you as a matter of fact. By our conversation: You don’t seem to know what a limit is, you don’t know the difference between natural and real numbers, you don’t know the formal definition of infinity, and you don’t know any applications of calculus, the subject built around that definition. So yeah, I have a really hard time believing that you’ve ever taken a college level math class, or even paid good attention in your highschool math classes either.
You’re not teaching me anything other than things I know aren’t true on a universal level. Our taught math is completely based and adapted around smaller scale numbers and that’s why you don’t learn how infinity actually works cause for what you’ll use it it will seem correct at your scale. But not on a larger universal all-included scale. At that level you need to basically be able to grasp the actual concept of infinity,… 🤷♂️
Try doing something more than your basic calculus.
y = 1/x. Then ask the question: where does this graph touch the x axis? The answer is both + infinity and - infinity. In other words the reciprocals of + and - infinity are both zero, causing + and - infinity to look as being equal.
Another interesting way of viewing this is as follows:
Many graphs are continuous, i.e. there is one line continues without breaking. However this graph is discontinuous at the x and axes which it never meets …… until + or - infinity.
Now a way of looking at how these two separate parts of this hyperbola could join to make one continuous line would be to look at the x and y axes as being curved (with an infinite radius) to ultimately join up. If this occurred then -infinity would join up with +infinity on both axes, and the graph would be a continuous function in both vertical and horizontal directions.
In some ways it is a natural way to look at it, as it is said that space is curved anyway, so in reality + and - infinity seem to be the same thing.
Now go educate yourselves instead of insultingly arguing bs, thanks.

Nothing in my phone is either infinite, nor negative.

Says the guy who claimed infinite was ever-expanding. 😅
That’s how you approach it, with ever increasing real numbers. Take a calculus class, I’m done teaching you for free
