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
d²y/dt² + dy/dt + y = xsolve for y
derivitives...
I dont understand them
differentials
are the dy/dt not derivatives?
yeah
nvm
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 = xis alot easierwhy 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
Kappa
the quadratic formula is actually used to solve for zero
(-b +/- rad(b^2 -4ac))/2a
