I think everything should still work though

At least in TI-BASIC summation can use complex numbers

No wait... rounding errors with the pi*i*[large number]

what is the square root of i

Whoops, that's not google

@ETHproductions (1+i)/sqrt(2)

Whoa, how does that work?

You know the unit circle, right?

Calvin's Hobbies

@ETHproductions Square it

7:07 PM

@Thomas Yep, just learned it recently

Okay, think about this: To get the square root of a number on the unit circle, you start at 1+0i, and go halfway to the number on the unit circle.

El'endia Starman

@ThomasKwa: ln( (1+1/x)^z / (1+z/x) ) = z*ln(1+1/x)-ln(1+z/x), right?

@El'endiaStarman Yep

@ETHproductions So to get the square root of -1, you go halfway around the top of the unit circle

that's i

A small challenge for those on the PPCG MC server: chat.stackexchange.com/transcript/message/25428540#25428540

El'endia Starman

@ThomasKwa Tested that formula and not only is it longer, it's less precise.

6 bytes longer, that is.

7:13 PM

@ThomasKwa You explained what 5 does, not why you didn't just use 1.

@ZachGates Oh, the I/O pin can't be assumed to stay at 1

So the 5 insures that if it's 1 the first time, the register is 1 forever

@ThomasKwa Ah, ok. Thanks for clarifying. That makes a lot of sense, haha

Is this still the rule that if you have a scoring system that deviates from number of characters, then you cannot use the code-golf tag?

@flawr You mean bonuses or something completely different?

(also, it's bytes)

No I mean apart from bonuses, like lets say every e you use in your code counts twice?

7:20 PM

hmm

I don't know, but I don't think code-golf is very strict

The reasony why I am asking:

A: Sandbox for Proposed Challenges

The Holey Scriptures Because it is Christmas soon it is time to take a deeper look into the hol(e)y scriptures, or more precisely holey characters. Holey characters, are (printable ASCII) charactes with holes. Among there holey characters there are the very-holey characters called arc-characters...

And I thought it would be fun to use a system based on the 'holeyness' of the code=)

@ThomasKwa Ah, so it's the same when starting with i instead of -1?

@VoteToClose That's amazing.

Why are there so many depressed equations? :( (Seriously, how can an equation be depressed?)

@AlienG Because (given that it's an n-th degree equation) the coefficient of the (n-1)-degree term is 0.

@VoteToClose Haha, that's funny.

@El'endiaStarman I legitimately don't understand it. :D Plz explanz da matz.

El'endia Starman

The equation solver flow chart?

7:46 PM

@El'endiaStarman Is there some joke or is it just the chart?

@El'endiaStarman Good luck, I'll see you in a few hours.

._. Why.

I really like this solver, and I'm happy you've found it=)

El'endia Starman

@VoteToClose I was amused by how flawr linked to this flowchart with text that's a copy (I presume) of the already-there text in the textbox when editing one's profile.

@El'endiaStarman =)

7:48 PM

My Stack Snippet interpreter for Japt has 7 votes \o/

El'endia Starman

This flowchart is really well-laid out. Seriously.

I was saddened by this flowchart

Too many NOs.

El'endia Starman

lolz

@Hipe99 Try this instead.

@El'endiaStarman That is what I thought too, the design might be a bit better but the idea behind this layout is quite good, once you look at it in detail!

I found this once on reddit, but I was never able to find the source.

El'endia Starman

7:51 PM

Google image search?

All sources are Pinterest. Hmm.

Who pins flowcharts?

Well the oldest source I've found was on mediacrush.ru, but it isn't offline anymore.

The only step that I am not completely happy about is the step from the depressed quartic to the monic cubic.

El'endia Starman

@Hipe99 Tag line: "Discover and save creative ideas"

Does anyone of you actualy use pinterest?

El'endia Starman

not me

7:54 PM

nope

I just have a 'inspiration' folder in my files where I just download images I like/find interesting/thought-provoking.

@El'endiaStarman The default text is "Apparently, this person prefers to keep an air of mystery about themselves".

El'endia Starman

@VoteToClose What about when you're editing?

:D

@VoteToClose Should I change it then?

7:55 PM

@flawr ¯\_(ツ)_/¯ It's your profile.

@El'endiaStarman Idk. I'll check.

Q: reducing depressed quartic to cubic polynomial

Recently I found this lovely algebraic equation solver flowchart online. What I do not understand is how to get from the Depressed Quartic (top right) to the Monic Cubic polynomial (the path where $\alpha_1 \neq 0$). I see that the intermediate equation $(u^2+[\alpha_2+y])^2=\dots$ is basically e...
