and there was no t in the original

legorhin May 7, 2016 9:21 PM general

nvm

legorhin May 7, 2016 9:21 PM general

whoops

Rex Bot May 7, 2016 9:21 PM general

d²y/dt² + dy/dt + y = x

legorhin May 7, 2016 9:21 PM general

y''+y'+y=x

legorhin May 7, 2016 9:21 PM general

thats better

Rex Bot May 7, 2016 9:22 PM general

solve for y?

legorhin May 7, 2016 9:22 PM general

its the same thing

Rex Bot May 7, 2016 9:22 PM general

y = x - y'' - y'

Rex Bot May 7, 2016 9:22 PM general

Kappa

legorhin May 7, 2016 9:22 PM general

again I'm wrong

JustinTrudeau May 7, 2016 9:22 PM general

legorhin May 7, 2016 9:22 PM general

adding t makes that too complicated

legorhin May 7, 2016 9:22 PM general

not what i meant

legorhin May 7, 2016 9:23 PM general

y''+4y'+4y = x

is alot easier

Rex Bot May 7, 2016 9:24 PM general

why is there a random floating apostrophe?

Rex Bot May 7, 2016 9:24 PM general

or is that like a double prime or something?

legorhin May 7, 2016 9:24 PM general

yeah

Rex Bot May 7, 2016 9:25 PM general

y = (x - y'' - 4y')/4

Rex Bot May 7, 2016 9:25 PM general

Kappa

JustinTrudeau May 7, 2016 9:25 PM general

Rex Bot May 7, 2016 9:25 PM general

how does this even work

legorhin May 7, 2016 9:25 PM general

i forget

legorhin May 7, 2016 9:28 PM general

first you put all the y differentials on one side and solve that for zero

Rex Bot May 7, 2016 9:28 PM general

what about the x?

legorhin May 7, 2016 9:28 PM general

more work

legorhin May 7, 2016 9:32 PM general

it involves itegrals and some stuff you need to memorize

Rex Bot May 7, 2016 9:32 PM general

integral proteins?....

Rex Bot May 7, 2016 9:32 PM general

Keepo

JustinTrudeau May 7, 2016 9:32 PM general

JustinTrudeau May 7, 2016 9:32 PM general

legorhin May 7, 2016 9:33 PM general

the quadratic formula is actually used to solve for zero

Rex Bot May 7, 2016 9:33 PM general

(-b +/- rad(b^2 -4ac))/2a

Rex Bot May 7, 2016 9:33 PM general

that?

legorhin May 7, 2016 9:34 PM general

yup

Rex Bot May 7, 2016 9:34 PM general

neat

legorhin May 7, 2016 9:34 PM general

only you use the order of differentiation instead of the exponent

legorhin May 7, 2016 9:35 PM general

so

y''+2y'+2y=0

reduces to

1,1

legorhin May 7, 2016 9:39 PM general

then because magic you get

y(t)=c1e^(t)+c2te^(t)

Rex Bot May 7, 2016 9:39 PM general

KALEC WAS RIGHT

Rex Bot May 7, 2016 9:39 PM general

MAGIC IS MATH

legorhin May 7, 2016 9:41 PM general

and my solution is apparently wrong

legorhin May 7, 2016 9:41 PM general

whatever

Rex Bot May 7, 2016 9:42 PM general

0/10

legorhin May 7, 2016 9:42 PM general

its been a year since i've done math

Rex Bot May 7, 2016 9:42 PM general

you should have your monacle revoked sir

legorhin May 7, 2016 9:42 PM general

I have to do it next year in Linear Systems II

legorhin May 7, 2016 9:43 PM general

signal processing is easy thankfully

if you haven't read inheritance you should

Rex Bot May 7, 2016 9:46 PM general

never got to read eragon

Rex Bot May 7, 2016 9:46 PM general

was going to for my senior thesis but then someone took it before me

Rex Bot May 7, 2016 9:46 PM general

so I am reading game of thrones instead

Rex Bot May 7, 2016 9:46 PM general

where all the dragons are already dead...

Rex Bot May 7, 2016 9:46 PM general

legorhin May 7, 2016 9:47 PM general

thats a major plot point

legorhin May 7, 2016 9:47 PM general

not really a spoiler

Rex Bot May 7, 2016 9:47 PM general

no

Rex Bot May 7, 2016 9:47 PM general

its like the 2nd chapter that that is revealed

Rex Bot May 7, 2016 9:47 PM general

except

Rex Bot May 7, 2016 9:48 PM general

things might happen with some stones

Rex Bot May 7, 2016 9:48 PM general

that are warm for some reason

legorhin May 7, 2016 9:48 PM general

are you talking about game of thrones or eragon?

Rex Bot May 7, 2016 9:48 PM general

no spoilers plz

Rex Bot May 7, 2016 9:48 PM general

game of thrones

legorhin May 7, 2016 9:48 PM general

all the dragons are dead in eragon too

Rex Bot May 7, 2016 9:48 PM general

but not the blue one

Rex Bot May 7, 2016 9:49 PM general

saphyria was it?

legorhin May 7, 2016 9:49 PM general

saphira

legorhin May 7, 2016 9:50 PM general

if you look at the covers of all the books, you'll notice some different colors

Rex Bot May 7, 2016 9:51 PM general

yeah I would assume there are other dragons alive too

legorhin May 7, 2016 9:51 PM general

maybe

Rex Bot May 7, 2016 9:51 PM general

only maybe

legorhin May 7, 2016 9:52 PM general

i don't want to spoil anything

legorhin May 7, 2016 10:06 PM general

apparently Paolini is a Minecraft addict
