Could somebody figure out what the limit of this sequence is? Something like the ultimate meme.

@slacktoid@lemmy.ml avatar

The correct way to pronounce it too

onion ,

Kansas to the minus one? One over Kansas?

Wilzax ,

Kansas^-1 (x) not kansas (x)^-1

onion ,

So one over Kansas times x not Kansas times one over x?

Wilzax ,

Kansas is a function name, not a variable in this notation.
Otherwise it would be (Kansa/s)(x) which simplifies to (a^2) (k)(n)(x)

mexicancartel ,

Kansas inverse?

Wilzax ,

Yeah it's a play how arcsin(x) = sin^-1(x), arccos = cos^-1(x), and arctan = tan^-1(x)

Arc kansas

America explain!

HakFoo , in yeah whats wrong

I like it.

Read the "1" unit side as "move left 1 unit" and the "i" side as "move up i units", and the hypotrnuse is the net distance travelled.

The imaginary line is perpendicular to the real line, so "up i unit" is equivalent to "right 1 unit". The two movements cancel out giving a net distance of zero.

there is... A lot wrong with that

Why do you hate fun

Yep. A vertical line segment above A with length 𝑖 is a horizontal line segment to the left that's 1 unit long. So, the diagram needs a "not to scale" caveat like a map projection, but there's nothing actually wrong with it, and the triangle's BC side is 0 units long.

MachineFab812 , (edited )

i= √(-1) = imaginary number
(1^2) + (√(-1))^2 = 1 - 1 = 0 7

At least, I thought that was the idea in the OP.

Also, for your version, on a number line or Cartesian plane, the distance from -1 to 1 is 2, not 0

mozz Admin ,

Yeah. We were making a joke about the complex plane -- you could say that measuring the hypotenuse of a triangle is equivalent to measuring the distance between points |AB| and |AC|𝑖 on the complex plane. That definition actually makes quite a bit of sense, and I think by sheer coincidence it's possible to misunderstand how to do it and wind up with a way of looking at it where the hypotenuse of a right triangle with sides 1 and 𝑖 would work out to exactly 0. Which brings it back into concordance with OP's (also wrong) Pythagorean presentation of it.

It obviously doesn't really work that way, but it's hard to see necessarily anything wrong with it, which makes it a fun math thing.

Yeah. I cheated. You have to either deliberately misunderstand how to measure vectors or else drop a minus sign for it to work my way.

(Or, from my previous example, you could just frame it as you're getting the hypotenuse by measuring between |AB| and -|AC|𝑖 instead of the way I framed it -- but that makes it more obvious that you're fishing for a particular answer.)

MachineFab812 ,

I liked your other reply better, but either way I still have more to learn. ie, I had no idea what the complex plane is.

mexicancartel ,

If so moving down the imaginary line should be equivalent to miving left but then the answer must be 2 units long

But (-i)² is also -1 and it still results in 0

badcommandorfilename , in Science memes

No YOU times infinity plus ONE!

threelonmusketeers ,

I use the axiom of replacement to construct a set of ordinals which come after "infinity plus one". Your move, sir.

theroastedtoaster , in Kowalski, temperature analysis

Fibonacci/Golden ratio = 1.618
Kilometres in 1 mile = 1.609

Conversion is off by less than 1%, not bad at all

Evil_Shrubbery ,

Yeah, it's nice and mysterious the first moment you hear about this but all the romance is gone once you think about how it works.

kogasa ,
@kogasa@programming.dev avatar

By far the most complicated part is the fact that the ratio of successive terms in the Fibonacci sequence approaches a specific number (which happens to be the golden ratio, which happens to be close to the ratio of km/mi).

When you take gravity into account then it makes way more sense this way. Thanks for sharing, will be visualizing this way going forward

What is the point of chili without meat? It would just be a bowl of beans and spices (or just a bowl of spices since beans really don't belong in chili).

I get the joke but you missed my point.

Still waiting for Chili tan carne.

AtomfriedMegaforce OP ,
@AtomfriedMegaforce@lemmy.world avatar

rotate your phone 90 degrees clockwise.

Resol ,
@Resol@lemmy.world avatar

Yay thanks

Ironfacebuster , in Best served hot. At 90 degrees (Celsius!)

It took me too long to realize the other one said "cos" and not "con"

I was like "why tf does rotating chili 90 degrees make it sinful?"

Daxter101 , in Best served hot. At 90 degrees (Celsius!)

This, together with the dish Chilli con carne, implies the existence of Chilli sis carne

NeatNit , (edited ) in Had to learn it the hard way too many times

You still have to prove that the integral exists, i.e. that from x=0 to x=∞ the integral is some number (not ∞ and not indeterminate). So it's not a total waste of time.

Edit: oh, the limits aren't ±∞ so if the function has no vertical asymptote in the range, it's a given.

threelonmusketeers , in Best served hot. At 90 degrees (Celsius!)

I wonder what the other four trig functions would look like...

AtomfriedMegaforce OP ,

me too, it was literally keeping me awake this night

kittenzrulz123 , in Best served hot. At 90 degrees (Celsius!)

I love this

I feel like we didn't need the arrow
