0/0 Anything divided by zero is undefined - Physics Forums
May 11, 2005 · 0/0 is also "undefined" but many texts use the term "undetermined" to distinguish that it is a special case: 1/0 is "undefined" because saying 1/0= a would be the same as saying 1= a*0 which is not true, for any a. 0/0 is "undetermined" because saying 0/0= a would be the same as saying 0= a*0 which is true for all a.
Zero divided by Zero: A Dangerous Indeterminate - Physics Forums
Jun 4, 2004 · The difficulty with you logic is that you can't use "anything divided by itself is 1" to PROVE that something (in particular 0) divided by itself is 1! You COULD use "any non-zero number divided by itself is 1" to conclude that the limit of x/x as x-> 0 is 1 but unfortunately, as mathman pointed out, other sequences that wind up as "0/0" give ...
What Does 1 Divided by Infinity Equal? - Physics Forums
Mar 26, 2003 · for all practical purposes 1 / infinity = 0 ===== just thought of something! ok, start with 1 / infinity = x 1 = x * infinity ~~~~~ analyze this ^^ x must be a REALLY small number to get infinity back down to 1 i.e. x = .0000000000000000000001 aka an infinite number of 0's and then a 1? or an infinite number of 0's and then a 2?
Exploring the Concepts of Zero & Infinity - Physics Forums
Aug 30, 2007 · Sure, as x approaches 0, sin x approaches 0 while sin x / x approaches 1. sin x / (x*x) approaches is "undefined" (i.e. it approaches plus or minus infinity) as real x approaches 0. So, 1 / (x*x) at x = 0 is a much larger infinity than 1/x at x = 0. The former has a double pole there while the latter has a simple pole.
Divide a Number by 0: Is it +infinite or -infinite? - Physics Forums
Feb 20, 2007 · 1. What happens when I divide a number by 0? When a number is divided by 0, the result is undefined or infinite. 2. Is the result of dividing a number by 0 always positive infinity? No, the result of dividing a positive number by 0 is positive infinity, but the result of dividing a negative number by 0 is negative infinity. 3.
Dividing by Zero: Is it Undefined or Infinity? - Physics Forums
Dec 7, 2004 · (though, both functions agree when the arguments are both real) Of course, 0/0 is still undefined. In the extended real line, it is even incorrect to say that 1/0 = infinity. It is even incorrect to say that [itex]\lim_{x \rightarrow 0} 1/x = \infin[/itex] -- don't forget that when x goes to 0, x takes on both positive and negative numbers.
Why Isn't x/0 = x, Instead of Undefined? - Physics Forums
Nov 20, 2014 · Hi everyone, I'm Pre-Calc here and have a question about a concept that is troubling me. I know that anything divided by zero is undefined. However, I'm not sure why this is or what we even mean by it. To me, the more intuitive result would be that x/0 = x, instead of being undefined...
Proving 0/0 ≠ 1: Does Math Really Work This Way? - Physics Forums
Jun 7, 2005 · Now, today my friend who's a math person has come up with this 'theory' that 0/0=1. She presented two arguments to support her theory, first she said that 0!/0! = 1, then she said that anything divided by itself = 1, (x/x=1),
How many times stronger is a 8.0 earthquake than none at all?
Jun 18, 2024 · A magnitude 8.0 earthquake is 10 times stronger than a magnitude 7.0 earthquake and 100 times stronger than a magnitude 6.0 earthquake. It releases significantly more energy compared to smaller ...
Electric Potential Energy Question - Physics Forums
Nov 19, 2014 · ΔE K +ΔE E =0 The Attempt at a Solution Okay so I know that:[/B] The Electric force is in the same direction as the displacement, which means kinetic energy is increasing and electric energy is decreasing (ΔE K =-ΔE E) As they move to a really far distance, the change in electric energy is equal to 0 - E E1 as anything divided by infinity ...
