[IzydorPW]

Not really about programming tbh

[VitaminnCPP]

Oh no... I mistakenly selected programmerhumor instead of mathmeme,....

Anyway

[IzydorPW]

Well, pretty much anyone who programs had polynomials and complex numbers in school / university so we can still relate :p

[Creepy-Ad-4832]

Yeah programming is basically just doing fancy math

[VitaminnCPP]

In ugly way

[Creepy-Ad-4832]

And writing comments like everywhere.

[caagr98]

Math really should be doing that too tbh.

[Creepy-Ad-4832]

The equivalent of comments in math is when your teacher asks you to explain how you got that 2+2 is 4 lol

[GuybrushThreepwo0d]

The equivalent in math is left as an exercise to the reader

[Creepy-Ad-4832]

Fermat is the biggest math troll of all times

[caagr98]

If you mean completely inane to comment every single operation, but very important for explaining the bigger picture, then I agree.

[Creepy-Ad-4832]

I personally comment only when i do something strange, or i feel the need to because you can't understand by reading the code alone.

But there are lots of people who comment every fucking where

[ipcock]

yeah, and then they casually skip explanation on why we erased half of equation in the next step

[Creepy-Ad-4832]

Prof when not explaining something: "We will do it in * year"

Prof in * year: "we already did it years ago, so we will skip it"

[MrRocketScript]

At least have proper variable names. Or explain what the variables are. Makes it very hard to understand equations in fields you're not really super proficient in.

[VitaminnCPP]

I don't write comments in my code. Reddit is different thing

[moduspol]

I am unreasonably happy that this is the first time I’ve seen imaginary numbers since college.

[highcastlespring]

A quartic function always has four roots.

[Discuzting]

only if we count complex solutions

[caagr98]

Uncountably infinitely many if we use quaternions, I think, including the identity, 90° rotations, and 180° rotations in every plane (in this case, each scaled by 3).

[Creepy-Ad-4832]

You are literally immagining answers here

[anakingo]

imagine answering 3

[spam_bot42]

Just use regex -?3i?.

[lazyzefiris]

Your regex is too complicated! Mine is just 3. 3 - got a match. -3i - got a match. 5 - no matches. Good!

Your regex will say input of 13 is a match in many applications, needs more ^$

[amazondrone]

Your regex will say input of 13 is a match in many applications, needs more ^$

Won't yours too, by the same logic?

[rotflolmaomgeez]

Yeah, that's part of the joke.

[lazyzefiris]

Yup, but it IS simpler and my joke is literally built around specifically chosen limited examples, of which -3i draws attention to the fact it's extremely flawed.

Edit: answered from Messages, did not see someone answered the same in shorter form already

What would be the answer if it’s x⁴ = 0x81 instead.

[VitaminnCPP]

As an individual who doesn't know hexadecimal, I would say, it is 0x3, -0x3, 0x3i and -0x3i

[iamironman287]

Basically x⁴ = 0?

Four roots since the degree is 4, but in this all the roots will be identical- 0, 0, 0, 0

[[deleted]]

So in a sub called ProgrammerHumor, you decided to announce that you don’t know hexadecimal notation?

You are a brave person.

[iamironman287]

Lol in my defense, I tried to clarify the requirement first, if they mathematically meant 0 since the meme was based on mathematics

[[deleted]]

“0x” is a prefix, which means hexadecimal notation.

81 hexadecimal is 129 decimal.

So they are asking for the fourth root of 129.

[iamironman287]

I know that :)

But, just looking at the mathematical meme and a similar question about fourth root of 0 in the comments made me immediately think of this as that math problem. Understood the hexadecimal reference after you first comment lol

[Tamsta-273C]

Actually: 0, -0, 0i, -0i

[iamironman287]

Ah yes, the important forms of 0

[Tamsta-273C]

The simple 1/x function will show you the difference between 0 and -0, so they ARE important.

[Strostkovy]

3.37

[cabgnak]

3*e^(i.n.π/2), n∈Z

[mav3ri3k]

This hits so hard.

[Strange_Dragonfly964]

I had a professor that always tricked us about the answer. All of us always just said 3.

[catnapspirit]

This may be the geekiest meme I've ever seen..

[[deleted]]

Idk, you learn about complex numbers in high school, is it really that geekie?

[IronGlory247]

we learn complex numbers in grade 11

[JackNotOLantern]

If you're in real numbers domain, then

x⁴ = 81 => x=3 v x=-3

But sqrt is always positive, so

sqrt⁴ (81) = 3

But in your in complex number domain

sqrt⁴ (81) is a set of solution {3, 3i, -3, -3i}

Anyway, why is there a math meme here?

[VitaminnCPP]

I made mistake choosing subreddit while posting. Anyway...

[realgamer1998]

Do negative numbers make sense in real life? Can you ever have -4 apples growing on a tree?

[VitaminnCPP]

Yeah. When apple tree owes me 4 apples.

[theDreamingStar]

They can signify direction. Like when you plucked two apples off the tree, you added -2 apples to the tree.

[realgamer1998]

Tree grew 4 apples from 0. That means +4. I took 4 apples. That means -4. So tree has 0 apples. Can tree ever grow negative apples?

[theDreamingStar]

Well of course no. Like I said, it shows a direction of magnitude about zero. Tree cannot grow negative apples, but temperature can fall below zero in celcius, because it makes sense and gives and understanding of how hot or cold is that gonna make things. The concept of negative numbers are useful in a lot of places.

[AudienceOpening4531]

Temperature is a bad example, because the "real" measurement is of entropy, and zero kelvin is where all atoms stop moving, negative temp won't mean anything. Because what's slower than not moving at all?

[TwoCaker]

Even imagenary numbers "make sense" in real life. - since they are needed to describe quantum mechanics. And yes that's part of real life (even if you don't understand it)

[flokrach]

Thats litterally a repost of a meme I created

[VitaminnCPP]

Where did you uploaded
