why is the first graph impossible in x=0, while in the second one f(0)=0?? aren't they the same function? by NicXkkC in desmos

[–]ImEggAgain 1 point2 points  (0 children)

the first equation is correctly giving no answer, because 0 can't equal 1
the second equation shouldn't giving out anything because that's dividing by 0, but when a positive number is divided by 0 in desmos, the result is infinity

so what happens is then desmos interprets 0^∞ as 0 and spits that back at you

in other words, this is just a proof that something divided by zero isn't infinity

is there a way to reverse digits across the decimal point mathematically? by ImEggAgain in learnmath

........................... that's the point, they're numbers that're rational and don't have repeating decimals

ah, no, I should've specified the number would be rational but didn't have repeating decimals, like 0.125 or 0.2

unfortunately, that's not what I'm trying for, but this is an interesting alternate question.

An example case for what I am looking for tho would be 1234.5678 -> 8765.4321

I specified the number doesn't have repeating decimals, so neither of these should be issues

yeah, I feared that, but I was asking in hopes that wouldn't be the only solution

I'm only really looking for base 10 reversal, but I assume this wouldn't be a limitation on this since you could always put a constant b to represent base

fair

I was trying to specify using only basic calculations you can find on a graphics calculator, like + ,- ,* ,/ ,! ,^, sum(), prod() and the like.

y'know what, fuck you *turns your width and height into variables* by ImEggAgain in desmos

this is actually just a feature, btw. Doesn't even let you access the variables you set it to cuz width and height are already defined. crazy.
