this is not an easy question to answer it has to do with different ways you can approach this limit

Oh no problem @TuringTest , I understand the problem @lgbasallote thanks a lot
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.4
there are a few main reasons why: 1) it conflicts between the rule that a number divided by itself is 1; and the rule that 0 divided by anything is 0. thus it conflicts whether the value is 1 or 0. so you cant determine if it is 1 or 0. 2) another reason is because there are infinite values that will give you 0 when multiplied by 0. so you cant determine which number is the right one.

TuringTest Group TitleBest ResponseYou've already chosen the best response.4
for example\[\lim_{x\to0}\frac xx=1\]but\[\lim_{x\to0}\frac{2x}x=2\]but both are mathematically equivalent to \[\frac00\]in the l;imit hence if we admitted\[\frac00\]into the set of numbers and gave it a value it would be inconsistent in mathematics and destroy the whole system effectively.

\[\lim_{x\to0}\frac{x^2}x=0\]etc. it would be an "inconsistent formal system"

to easily understand this concept let's take an example of (10/2) which is same as 5, and (5/5) is same as 1, but we can't say (0/0) as 1 simply because 0 on numerator is equal to zero on denominator, and (0/0) is undefined..... we don't know what it is.

@lgbasallote why x/0 is undefined? curious

lgbasallote Group TitleBest ResponseYou've already chosen the best response.4
okay let's say for example x = 2 2/0 can you give me a number that when you multiply to 0 the answer is 2?

I think that technically both are undefined 1/0 is undefined but *not* an indefinite form 0/0 is an indefinite form. Is it also undefined? I think so...

i think the best term for 0/0 is indeterminate..
 2 years ago

TuringTest Group TitleBest ResponseYou've already chosen the best response.4
any division by zero is undefined, so x/0 is undefined 1/0 undefined and not indefinite 0/0 undefined and indefinite that's my understanding
 2 years ago

dumbcow Group TitleBest ResponseYou've already chosen the best response.1
my way of thinking is undefined refers to an infinite number that is not defined but we relatively know its really big or really small(big negative) indeterminate means we have no idea what the value is

I meant "indeterminate" when I said "indefinite" :/ so do you say that 1/0 is indeterminate or not?

no i would say its not indeterminate because we know the limit of 1/x as x>0 is infinity

mathematicians *define* \(0^0=1\) because of a number of arguments btw note that your reference is Thomas and Finney 1996, pp. 220 and 423; Gellert et al. 1989, p. 400 and there are other equally reputable books and references that disagree if you read the article I linked you too, or some of those linked to it.

it is just very debated ti this day is all I generally treat it as undefined as well

Herp_Derp Group TitleBest ResponseYou've already chosen the best response.0
For x not equal to 0, x/0 is defined (as a number, not necessarily as a limit) in a 1point compactification of the reals (the projectively extended real numbers) or the complex numbers (the extended complex plane), and is equal to infinity. However, 0/0 (as a number) is still undefined in these settings.

dumbcow Group TitleBest ResponseYou've already chosen the best response.1
btw the limit of x^x as x>0 is 1 , which i believe is a strong argument for equating 0^0 to 1
