Okay done, I think you should have edit available now

The math rendering is a little slow when you open a page, and I might be able to fix that, but I am scared to change things since it works and I don't want to break it lmao

Ahh actually where do you live, probably perfect for you haha

My server is in California I think

Ohh very nice, when does the program start?

Oh I saw that, the one where they just expect you to be good?

That's awesome though, who were you teaching? I can't remember if it said in the blog, is he a uni student?

Oh okay, HS students should be fine then to just rock up, as long as you get to see some sort of plan

My ex-gf tutored some kid in physics and he just rocked up with no plan the first time and it didn't go well - she just tutored him on other stuff from his text-book and said, "Next time, have a plan". Second one went much better :P

Yeah that's actually pretty weird that they haven't given you any direction. But my wealthy friends had parents that just liked to have tutors for their kids for seemingly no reason

I'll add you as admins if you make a profile on my website Here

Okay talk soon :)

I have added the admin rights for you @Sami

For linking internally, you just use [[Page name you want to create|Text you want to show]]

Sad to lose a member @jcprx

Did you see the things I linked above? Maybe they will make you feel a little better about the math. They really help with the definitions in getting the geometric intuition running, or maybe you were already past the polyhedral fans

Oh sorry I meant that for jcrpx

I should have tagged it haha

@SamiBrooker Usually you are meant to click the arrows

@EricStucky Oh yes, I originally was showing it to Sami

@SamiBrooker If you put your mouse over a chat message, on the very right of it

Hahahaha

Yes that's crazy

I would feel overwhelmed too

@jcprx Have you answered Eric's initial questions?

Well that's a good start for sure

If you mouse over your message, on the left there is an arrow for a drop down menu that has edit on it

@jcprx I think the math level shouldn't matter much, it seems like stuff most math majors wouldn't have dealt with. I have done essentially no geometry related things at any point

The only things that have helped me at all were with my confidence, like not being afraid of seeing commutative semi-ring with identity and such

@jcprx Yes, I have never encountered half-lines, cones, convex hulls, convex sets

Oh I guess the set theory might be harder, since point-set topology really gets you to appreciate that, so I see what you mean

Anyway I think the teams communication probably didn't help. If you realised that we are all really in the same boat, and it is hard for me, you'd probably feel better

I felt overwhelmed too, I couldn't find the definitions for anything lmao

Indeed :P

Eric's probably thinking "I said all this already..."

I don't think it can be forced unfortunately

It's sort of a, 'I feel like I suck, I don't want anyone else to know' sort of thing(for me atleast)

Haha yes true, I agree

I personally feel a lot better now, and it helps that I found those links I showed above

Hell, I'm probably behind you since life has been distracting me

My goal is to try to get those questions done by next week

Yeah when I was doing engineering, the group meetings seemed really important for breaking the ice

(admittedly, they usually involved random people drinking together)

Hahaha

Ahahahahha

Well I am going to dig into some math now, gotta get these questions done + prep for 4 all four classes

Wait I am confused by your interpretation and mine

Wait can you clarify 'that wasn't the intention'?

Where were you intending to focus the project?

@EricStucky I shall be. Cya then :)

Stupid question: A face of a convex polyhedral cone, lets say in $\Bbb R^3$, refers to any of the flat regions created by the straight lines joining two half lines from the origin, right?

I.e. the red region

I mean it soudns right, but I can't find a solid definition xD

Hmm faces are defined differently by dimension - never encountered that before

@SamiBrooker You mean in $\Bbb R^3$?

Well from what I understand, a cone is a set of half lines, as well as every point between any of these points. I.e. If we have only two half lines from the origin in $\Bbb R^3$, then we have three cases 1) they are in the exact same direction, and we get just the half line, 2) They are in exact opposite directions, and we get a full line, 3) They are facing at some less than 180 degree angle from some perspective, and we get a pizza slice 'plane'

Haha no worries at all!

I drew like 30 pictures last night

I started in R^2 which helped heaps

Then I haven't got a nice mental picture yet of n-halflines in R^3 yet since I got caught up in the face definition haha

And in R^2 if you have n-lines, and the sum of all of the angle differences is less than 180, you just get a pizza slice with the edges being the greatest angle different

If that makes sense

And if the total angle difference is greater than 180 you get all of R^2

Then you have the single half-line case and the full line again

I don't know why linking isn't working properly for me

Hopefully @EricStucky can come and clear up the faces definition thing for me xD

Like two halflines that look like a single line together?

I think their convex hull is the same as just the set containing all points on the two half lines

I.e. the convex hull changes nothing

Like if they were lying almost colinear, you would get the 'pizza slice' of all points between them

But if they are colinear, the convex hull should just be the line

Yep, I think in that case we need three lines

Say three lines that divide the axis into three

R^2 is two dimensions

Okay haha sorry I should say it

That's good, since I can't draw with this sketch pad haha

No I know what you mean

In $\Bbb R^3$ yep, three coplanar half-lines will follow the same cases

That was me too haha

4:45pm xD

Like 1am there?

This stuff is actually really awesome

yeah haha

@EricStucky If you would prefer, I imagine I would be capable of creating another wiki off of my server, strictly for official purposes(that would run side by side on the same domain, like alexpclark.com/crpx/index)

Otherwise in terms of making it disjoint you could just ammend crpx onto the start of everything(I'm just thinking about your 'keep the project somewhat self-contained' comment)
