Anyways, fuck you people, I have a physics assignment you are distracting me from Kappa

does it involve multiplying mass by the speed of light squared?

don't do it on a plane

No, it involved researching a bunch of applications of magnetic, gravitational, and electric fields

like hoverboards?

gravity kills a lot of people every year

its dangerous

So does water

you shouldent do dangerous things on planes

dihydrogen monoxide is now banned on planes

so you have to buy your dangerous chemicals from them instead

$$$$$$$$$$$$$$

the laws of science are now banned on planes for being dangerous

Kappa

solving for y is now banned

no fun allowed

you can only solve for x on planes

thats algebra and calculus

in differential equations you solve for y

solving for y is statistics Kappa

so what are differential equations and why do they use y anyway?

its when there are multiple levels of differentials in one equation

do I learn this in calc?

calc 4

so not ap calc

deffinitely not

well I guess he was a coleg professor

solve for y

derivitives...

I dont understand them

differentials

are the dy/dt not derivatives?

yeah

y = -d²y/dt² - dy/dt + x

do I win?

differentials are dt, dy, dx...

and no

hold on

I think I could do something here...

y(x) = c1 e^(-x/2) sin((sqrt(3) x)/2)+c2 e^(-x/2) cos((sqrt(3) x)/2)+x-1

i used the internet because I can't be bothered to look up how to solve these

this is as far as I got: y = d (-dy -y +xt^2)

thats not valid in any way

I probably broke some rule somewhere

and there was no t in the original

nvm

whoops

d²y/dt² + dy/dt + y = x

y''+y'+y=x

thats better

solve for y?

its the same thing

y = x - y'' - y'

Kappa

again I'm wrong

adding t makes that too complicated

not what i meant

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

is alot easier

why is there a random floating apostrophe?

or is that like a double prime or something?

yeah

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

Kappa

how does this even work

i forget

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

what about the x?

more work

it involves itegrals and some stuff you need to memorize

integral proteins?....

Keepo
