Congrats, your girlfriend is imaginary.

This meme become even better

[–] Sibbo@sopuli.xyz 43 points 1 year ago (3 children)

Is this an I, or a hint that her feelings are complex?

[–] Seraph@kbin.social 37 points 1 year ago

Imaginary feelings

[–] bstix@feddit.dk 10 points 1 year ago

She misses the imaginary root.

[–] arin@lemmy.world 5 points 1 year ago

Complex relationship

i will always be current. j will always be the square root of -1. Nothing will ever override this in my brain

Capital J is current density, lowercase j is √1

I don’t remember nearly enough science stuff to get most of the jokes here. Oh well.

[–] Afghaniscran 31 points 1 year ago (2 children)

If I'm not wrong, I think the square root of minus 1 is an imaginary number which is represented by i

Don't ask me anymore questions about this if you want real answers because I genuinely don't know any more.

[–] finestnothing@lemmy.world 19 points 1 year ago (1 children)

Yep, sqrt(-1) = i. Powers of i are actually really neat imo since they form a loop: i^0 = 1
i^1 = i
i^2 = -1
i^3 (or i^2 x i or -1 x i) = -i
Now the loop starts:
i^4 = i^2 x i^2 = 1 x 1 = 1
i^5 = i^4 x i^1 = 1 x i = i
etc
Any evaluation of i to the power k boils down to i^(k%4). For example, i^726 = i^2 = -1. I know this was super useful in calc 1 or 2 and not used for any of my other math classes, it's just a fun concept to me

Powers of (1/√2 + i/√2) form a nice loop as well :)

Okay, that’s a deal. And thanks!

this guy and his imaginary girlfriend. He sure has a complex relationship

[–] doctorcrimson@lemmy.today 19 points 1 year ago (1 children)

She really did miss him with that one.

Maybe

∫~0~^M^ r^2^ dM

Would work better?

[–] Masimatutu@mander.xyz 16 points 1 year ago

Well ackshuwally uppercase I denotes the identity matrix :P

[–] Assian_Candor@hexbear.net 12 points 1 year ago

Imaginary girlfriend lmao

[–] froh42@lemmy.world 7 points 1 year ago (2 children)

As my math teacher said:

Ich ziehe meine Wurzel aus einer Unbekannten.

Sorry, I don't think this works when translated.

[–] Johanno@feddit.de 4 points 1 year ago (1 children)

I pull up the root of an unknown.

[–] froh42@lemmy.world 6 points 1 year ago

Meaning a: I take the root of a variable

Meaning b: I pull my "root" out of an unkown woman

[–] plague_sapiens@lemmy.world 2 points 1 year ago

Ich kenn den anders. Wahre Mathematik ist es, wenn man schon morgens seine Wurzel aus einer Unbekannten zieht xD

[–] embed_me@programming.dev 7 points 1 year ago

Kept reading that as iota. "I ought to" miss you

[–] Masimatutu@mander.xyz 2 points 1 year ago

In my humble opinion e^iτ^ is a lot prettier

[–] bloubz@lemmygrad.ml 2 points 1 year ago (1 children)

I don't really like this syntax. √ should be used on positive reals only

That's my take, change my mind

[–] Damaskox@kbin.social 2 points 1 year ago

Reading the comments here made me think about this!
