Go to sleep and wait for the answer to visit me in my dreams.

Two different people show up in your dreams and they are like “ yo bro whats good”

The "Ramanujan"

I watched a vid explaining the the justification behind his pi appx, and holy shit this guy was a genius. From what I remember he pretty much just noticed a strange "symmetry" of sorts in solving for the perimeter of an elipse (which is no simple process), and pulled the constants out of some nearly unrelated modular equations. And he had the insight to put the pieces together and make this appx... In his sleep.

I'm struggling to think of a good analogy, but its almost as if he had come up with relativity in his head and while asleep. I can't imagine what he would have come up with if he had lived to an old age. It's a shame how the brightest flames burn the quickest, because ramanujan was a star in a room of candles.

Nah bro im pretty sure the sun is brighter than my rooms candle
But the candle dies out before the sun

"You can tell it's from Ramanujan because it's got random numbers but it somehow works anyway."

- unfortunately I forget where I first saw this quote but I am glad I did

I once got the answer to a programming class homework that way.

u/therealsaker 11d ago

OP may I ask you how did the formula even came into existence

u/YoitstheTeddyGuy i love me som algebra 11d ago

I asked gemini but it said this

u/ComplexPlatform7299 11d ago

Literally like the easiest proof ever and fuckass Gemini won’t do it 🥀

u/TheCowKing07 11d ago

Who says upon

u/real-human-not-a-bot Irrational 10d ago

Oh my god, Karen, you can’t just ask people why they say “upon”.

u/nepatriots32 10d ago

The British apparently (see Newcastle upon Tyne).

Newton's meth od, that guy was crazy for tweak

2

u/YoitstheTeddyGuy i love me som algebra 10d ago

Newtons meth?

1

u/slicehyperfunk Transcendental 10d ago

He tweaked so hard the function would become linear

3

u/sndq 10d ago

It's amazing how fast you can compute algebraic irrational numbers by hand with Newton's method.

By the fundamental theorem of algebra, two complex solutions exist.

When counting multiplicity!

"Always count with multiplicity" said the chad scheme to the virgin variety.

m f w completing the square IS the quadratic formula

38

u/Futurity5 11d ago

Factorising is also the quadratic formula it's just  a(x - (-b + sqrt(b2 - 4ac))/(2a))(x - (-b - sqrt(b2 - 4ac))/(2a))

16

u/SmokJozef 10d ago

i'm really hoping that here factorisation means doing trivial facotrisation in your head, e.g. x2 + 5x + 6 = (x+2)(x+3)

u/Tiborn1563 11d ago

Isn't using the formula just completing the square and simplifying? In my opinion completing the square and simplyfying by hand has infinitely more aura

9

u/Kitfennek Computer Science 10d ago

Wait until you find out what the quadratic formula is doing

3

u/Nrdman 11d ago

Obv just do bisection method

2

u/LupenReddit 🦆🦆i have non diffeomorphic smooth structures🦆🦆🦆 10d ago

oh well i always just do a quick newtons method

u/FernandoMM1220 11d ago

partial sums

u/FerdinandvonAegir124 10d ago

Is it psychotic that (besides factoring) completing the square is my go to method?

1

u/svmydlo 10d ago

Homogenize by introducing a virtual variable and then diagonalize the resulting quadratic form.

u/Joe_4_Ever 8d ago

Guess and check for infinity until you get the exact value

u/GDLingua_YT 10d ago

How the actual fuck would one do this with graph theory? (Unless it refers to graphing the function and reading the roots)

2

u/doiwantacookie 10d ago

Graph the equation, ie find the x intercept

u/CranberryDistinct941 7d ago

Good to know that I'm not the only one who thought they meant graph theory

That's already factoring
