@median trail pogchamp
median trail
okay so remember how abs value is defined
when x is equal or greater than zero
x is is positive
then you have to solve for -x when x is less than zero
so you have
x^2 - 5x + 4 >= 0, x >= 0
(x-4)(x-1) >= 0
x1 = 4
x2 = 1
and this is fine since x is greater than zero
now
when x is less than zero
(-x)^2 - 5 (-x) + 4 >= 0, x < 0
x^2 + 5x + 4 >= 0, x < 0
(x+4)(x+1) >= 0
x3 = -4
x4 = -1
and this is fine since our x values are defined to be negative
so you have 4 solutions to what you have in the pic
real imp
yes but what confuses me is
when only x is absolute
does the whole thing go absolute as well
median trail
it doesn't matter, yes because the x are the same
x^2 - 5 abs(x) + 4 >= 0
x^2 is like abs(x)^2
abs(x)^2 - 5 abs(x) + 4 <= 0
(abs(x) - 4) (abs(x) - 1) <= 0
abs(x) - 4 = 0
when x >= 0, x is positive
x1 = 4
when x < 0, x is negative (-x)
-x - 4 = 0
x2 = -4
abs(x) - 1 = 0
when x>= 0, x is positive
x - 1 = 0
x3 = 1
when x < 0, x is negative (-x)
-x - 1 = 0
x4 = -1
real imp
uh
median trail
as you can see I get the same solutions
real imp
you confused me
ok so like
x^2 - 5 abs(x) + 4 >= 0 is the same as abs(x^2 - 5 x + 4) >= 0?
that's what im asking
median trail
no
median trail
you just have to remember how abs value is defined
what is confusing? so that I can address that specifically
median trail
so basically abs(x) is defined this way
so in order to solve for x what you have in the picture
you have to consider first when x is greater than zero
and then when x is less than zero
because that's how the function abs(x) is defined
fathom flame
median trail
he basically wrote what I sent a few minutes ago
you can not factorize having an abs value in the polynomial
so you have to find a way "to get rid of" it
and you do it by using the definition
median trail
ehmm no
you are just saying, okay if x is greater or equal to zero then x is positive so I don't need the abs value notation
fathom flame
i think he can see it more clearly if u prove it edsel
median trail
yea but in that case all the polynomial have to be surrounded by the abs value notation
median trail
you could do this:
real imp
+-a = b is the same as a=+-b
median trail
|x| <= (-x^2 - 4)/-5
(-x^2 - 4)/-5 <= x <= (-x^2 - 4)/-5
because all the stuff that's on the left have side have to be surrounded by the abs value notation
in order to what you showed be true
median trail
?
real imp
-((-x^2 - 4)/-5) <= x <= (-x^2 - 4)/-5
real imp
ok yes that i do get
median trail
you can not use those properties unless what's on the left hand side is surrounded by the abs value notation
median trail
and imo you shouldn't rely on that property since it's so time consuming that you'll be wasting a lot of time
median trail
you have to solve for abs(x)
then use the property
and then solve both inequalities
you can just use the definition and get all the values of x right away
as I showed you above
real imp
coolio
median trail
but in this case where the abs is like inside the polynomial
and the whole polynomial isn't surrounded by the notation
it doesn't make sense to use that property since you can just use the abs value definition
real imp
ok ok lets see if i can get to the result
median trail
yea exactly

what the fuck
@abstract scaffold are lines just the same thing as the linear combination of a vector and a point?
like
(x,y) = t(x0, y0) + (0, b)
for instance, let's assume x0 and y0 are 2 and 3 respectively, and b = 2
it's the same thing as y = 3/2x + 2
like if x = 1 then y = 7/2
so we got the point (1, 7/2), and if t = 1/2 then (x,y) = (1, 7/2)
:00000000000000
median trail
and it makes total sense that if a subvectorial space is a line it has to pass through the origin (0,0)
because if we let v1 and v2 be vectors that are parallel to the the linear combination t(2,3) + (0,2), and if v1 = (d, c) and (-d,a)
therefore
v1+v2 =/= (0,0)
vestal pine
median trail
v1 + v2 = (0,c-a)
and since it isn't the (0,0), this means I can not multiply none of the vectors by 0 because it's simply impossible to reach

a linear transformation is even better since it's what's taking place in this operation

you have one input matrix
and the i and j vectors would be the one of the slope and the one of the interception with the y axis
but we are not scaling the latter
just the former
if we would let both scale we get R^2

luego, refleja la parte del dibujo que todavía tienes en x=0.

pues hay cosas que necesitas hacer con cuidado, por ejemplo la regla de l'hospital y el limite de sin(x)/x, x->0
la razon por la que una persona necesita saber la prueba para este limite es que no se puede usar la regla de l'hospital aqui ya que primero necesitas saber la derivada de sin(x).... pero para saber la derivada, necesitas saber este limite, asi que es circular referencing.
por eso, hay otra manera para probar este limite.
without knowing some proofs, you might accidently circular reference.

why do you need to specify "single"?

abstract scaffold
@median trail i mean quiza necesitas numeros binarios para hacer algunas calculaciones en algebra modular.

I guess its just weird terminology
hollow wedge
no but I guess core speed is the same as clock speed right?
and if you have many cores you still just have a single clock speed
afaik
or a single max-clock speed
ocean otter
Yes but i think if you put all of the cores to work at max, the speed decreases
I guess single core speed means how fast is the core when not all of them are full of work

I didn't know that putting them all to max would lower speed
but then modern architecture is friggin complicated

then start doing your method ruffini. but in this case... you're done already.

because you already reduced it to x(x^2+2)

then start doing your method ruffini. but in this case... you're done already.
@abstract scaffold have i? i thought i couldnt use 0
for ruffini
abstract scaffold
porque si x^3 + 2x = 0
=> x(x^2+2) = 0
entonces x = 0 o x^2+2 = 0
abstract scaffold
if the question just said "factorise this", then don't say x = 0
real imp
that makes a lot of sense
yeah no
i just gotta find the roots
but if it were factorise this
then (x-0)=0
real imp
great thank you
abstract scaffold
if the question just said factorise x^3 + 2x
tu respuesta final deberia ser: x(x^2+2) nomas
abstract scaffold
factorise x^3 + 2x is different to
solve x^3+2x = 0
abstract scaffold
but with the second, you would use factorisation first to get your way to the solution
real imp
also quick question
log(a) + log(b) = log(ab) right?
what about log(a) * log(b)?
how do I solve the latter by hand?
gusty ermine
i don't think you can in many cases
abstract scaffold
so yeah, si es una ecuacion, escribe x = 0 {y si tambien quiere que busques raices complejas, resuelva x^2+2 = 0 tambien}
log(a)*log(b) no tiene otra forma
y si, log(a) + log(b) = log(ab)
gusty ermine
like that's the maximum it can be simplified
real imp
log(a)*log(b) no tiene otra forma
welp this is gonna be a messy matrix
abstract scaffold
si es log(1) o log(e), se puede simplificarlo mas ya que ln(1) = 0 log_a(1) = 0 {a^0 = 1} y log_e(e) = 1 {e^1=e}
real imp
Gross, just gross
abstract scaffold
that is indeed gross
no se si es correcto porque no se cuales ecuaciones con las que empazaste.
abstract scaffold
@real imp para y, tu numerador es correcto, pero el denomiador, no.
(log(a))^b no es igual a blog(a)
abstract scaffold
but either than that, parece que todo esta bien
abstract scaffold
yeah, it's just gross.
se puede cambiar log(4) a log(4) = log(2^2) = 2log(2)
=> log(2)log(4) = 2(log(2))^2
real imp
nice
abstract scaffold
pero todavia se ve feo
real imp
im not gonna go back and change it because its just too much work and too confusing
abstract scaffold
what u left it as is fine (apart from the denominator)
no he chequeado si x es correcto ya
ah. x has a cleaner form.

@ashen mist are you there?
median trail
okay
I have a networking question
when we say 192.168.0.1/24 means the the subnet mask is 255.255.255.0 so the host addresses will be in the last octet, right?
this also means that we can not vary the first three octet since they represent a network?
why is it thirty two in the second example of private addresses?
instead of 31
16 = 00001000
31 = 00001111
where does this additional 1 come from
ashen mist
/24 works out nicely because each octet contains 8 bits
ashen mist
if you look at the binary version of the net mask, the netmask is 11111111 11111111 11111111 00000000, which is 255.255.255.0
the netmask is 24 bits long, so you have 24 1's and 8 0's
for 172.16.0.0/12, the netmask is 12 bits long
so it's 11111111 11110000 00000000 00000000
you have 20 free bits to represent the hosts
if you look at the second octet of 172.16.0.0, itll be 0001 0000. The second octet of the net mask is 1111 0000, so you can freely edit the last 4 zeroes of the 2nd octet in the host address while still staying within the network mask
so the biggest address would fill in the second octet like 0001 1111
which is 31. (16 + 8 + 4 + 2 + 1)
ashen mist
LOL
median trail
but host addresses would go from 0000 0001 to 0000 1110?
ashen mist
I think the first address is reserved as the network address, and the last address is reserved as the broadcast address
so 172.16.0.0 is reserved, 172.16.255.255 would be used as broadcast
median trail
I thought network addresses had only 0 in the host portion
ashen mist
sí, no dije eso?

regarding broadcast, what's the difference between limited and directed broadcast?
ashen mist
hmm no sé. tendría que buscarlo
encontré una explicación
https://superuser.com/questions/1006915/what-is-the-exact-use-of-a-limited-broadcast-address
You are misunderstanding the use of directed and limited broadcasts. 255.255.255.255 is a limited broadcast: it is not passed on by routers, so it is really useful only to a member of a LAN to contact all other members of the same LAN. But routers will not forward these broadcasts because, if they did, these broadcasts would fill the whole internet. So they are useful, in Layer-3, and limited.
Directed broadcasts are represented by, for instance, 192.168.1.255. These are passed on by routers, because of course they are less invasive than 255.255.255.255, even though this feature is often disabled in real-world routers because it is easily abused (you'll see why in a second). If I am a member of of the subnet 192.168.1.0/24, then it makes little difference whether I use as a broadcast 255.255.255.255or 192.168.1.255.But suppose now I am a member of the subnet 192.168.2.0/24, and I want to send a broadcast to all members of a different subnet, say, 192.168.1.0/24. How can I do that? I cannot use 255.255.255.255 because that is restricted to the LAN of the emitter, 192.168.2.0/24 in this example, and thus it will never reach 192.168.1.0/24 because routers drop these packets. But, aha, I can use 192.168.1.255 from outside 192.168.1.0/24 to reach all members of the network with a single broadcast, because the router separating my subnet, 192.168.2.0/24 from the target subnet, 192.168.1.0/24 will pass these packets on.
subnets are nets that are connected to the same router but in different interfaces, right?
ashen mist
creo que eso es una manera de hacerlo
pues, un router puede estar conectado a varias redes a la misma vez también
subnet is just a division of a bigger network
so for 192.168.1.0/24, 192.168.1.0/27 would be a subnet

@ashen mist does this mean that a host assigns its IPv4?
ashen mist
Si tu computadora quiere usar DHCP, eso significa que quiere que un servidor de DHCP le dé una dirección de IP. Si ese servidor no existe o no está disponible, entonces automáticamente tu computadora va a asignarse a sí mismo una dirección de 169.254.0.0/16, lo cual está reservado para esto
Esto puede explicártelo mejor https://www.google.com/amp/s/whatis.techtarget.com/definition/Automatic-Private-IP-Addressing-APIPA%3Famp=1
real imp
I haven't read what you've been talking about
but just remember
DHCP basically gives IP automatically to the connected devices
that's just it
whenever you plug a new device with DHCP enabled, poof
new IP address, no need to do anything manually

@real imp yeh pero se necesita un servidor de DHCP para administrar las direcciones dados. La computadora que va a recibir la dirección IP no puede elegir su propia dirección para la red porque no sabe cuáles ya están usadas
ashen mist
por eso si no hay un servidor disponible o si la computadora no puede conectarse a ese servidor, va a elegir esa dirección reservada de APIPA
real imp
We did it in our pc maintenance class
ashen mist
DHCP requiere un servidor y un cliente
real imp
I mean sure, the school probably had a server
but we just used... the internet?
I mean I assume every single router has DHCP
Nowadays, ofc
I've made lanparties at home
ashen mist
podés configurar el servidor para determinar el rango de direcciones válidas para su red
ashen mist
creo que la configuración ya existe por defecto
ashen mist
pero si arranco una VM sin conectarlo con un router o servidor de DHCP (o si lo arranco sin conexiones de red), entonces va a darse la dirección de APIPA
https://en.wikipedia.org/wiki/Link-local_address
Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures as self-assigned IP addressing. For Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration. In IPv4, link-local addresses are normally only used when no external, stateful mechanism of address configuration exists, such as the Dynamic Host Configuration Protocol (DHCP), or when another primary configuration method has failed.[3] In IPv6, link-local addresses are always assigned (usually in addition to other addresses) and required for the internal functioning of various protocol components.[4]
@ashen mist I have a question, when working with IPv6 addresses, the local-link address of the router is the default gateway?
median trail
if I'm using IPv6 addresses, what's the default gateway?
@ashen mist
I think it's the link local address, but I'm not sure
median trail
and how many link local addresses does a router have? because each interface has an IPv6 address
but those IPv6 would be global?

@old shell Okay so... It's rather difficult for me to constantly pronounce my short a sounds (from my Spanish perspective: the vowel sound in man and the vowel sound in fun) the way he does. So I started to listen to ppl that pronounce the a in man more closely to an /e/, that way I can pronounce the vowel sound in fun (or love, or young) more freely. I don't know if I've explained myself well

so you would say that that short a sound is the difference between Paxman's accent and yours? @unborn wraith
