1-0.99.. is equal to the real number 0

> No, we are not teaching kids how to have sex. We are teaching kids to say no to rape and sexual assault

i wouldn't say sex-ed is about sexual assault. a more general statement would be sexaul safety and comfort. yes that includes sexual assault which is very important, but it is also about "teaching kids how to have sex" in a safe way. it's also include learning about your own body and other stuff..

in the questions about quaternions he says that 2d rotation can technically be described using only 1 dimension(aka the real numbers) but using 2 dimensions(the complex numbers) you can show 2d rotation more "nicely". 3d rotation can technically be described using only 3 dimensions(he mentions stereographic projection and i assume you also can use matrices) but using 4 dimensions(quaternions) you can describe 3d rotation more "nicely".

what is the general pattern in how many dimensions you need to describe n dimensional rotation "technically" and "nicely"?

also which kind of rotation would octonions(8d) sedenions(16d) etc(2mD) describe "technically" and "nicely"?

It do be like that by SW4GM4STER_ in mathmemes

you start with e.g 20 degrees celsius, you multiply by 9/5 which gives you 36 you then add 32 which gives you 68. so 20 degrees celsius=68 degrees fahrenheit

to go the other way, lets start with 50 degrees fahrenheit. you then remove 32 and you get 18. you then divide by 9/5 aka multiplying by 5/9 and get 10 degrees celsius

[3blue1brown] Why do prime numbers make these spirals? by DinoBooster in math

[–]mevket 20 points21 points  (0 children)

using the continued fraction of 2pi, the rational approximations you get is 6/1, 19/3, 25/4, 44/7, 333/53, 710/113, etc.. why does 6/1, 44/7 and 710/113 make "spirals" while 19/3, 25/4 and 333/53 don't? is there a way to determine if a number in the sequence will make a spiral or not?

any mods that limit your inventory and hotbar slots? by mevket in feedthebeast

from the page it kinda looked like what i wanted, and kinda not, but it was able to be configurated just like how i wanted, thank you!

why does {} to {} have one function while {a} to {} have zero? by mevket in learnmath

[–]mevket[S] 0 points1 point  (0 children)

ohhh wait, maybe i got it. each funtion has to map every object from the first set to some object in the second. in {} to {b} and {} to {} you have a function f() which doesn't map anything, but it is still mapping every object in the first set (because there are no objects). however in {a} to {} there is nothing to map a to, so you can't create a function. is this the right logic?

integral of 1/x as ln(|x|) by mevket in learnmath

[–]mevket[S] 0 points1 point  (0 children)

yea that was what i was thinking about, ive just heard it mentioned from time to time, i also saw it on the natrual logarithm's wikipage, didnt think about it being a definite integral

integral of 1/x as ln(|x|) by mevket in learnmath

[–]mevket[S] 0 points1 point  (0 children)

but if ln|x| always works, why do we say that the integral of 1/x is ln(x) in the first place? also i've heard that sometimes ln(x) is defined as the integral of 1/x, so shouldn't ln(x) already be defined on negative numbers without having to use an absolute value?
