Sierpinski's Triangle
« on: October 08, 2010, 11:19:04 am »
well, so couple days ago, my teacher was talking about the Sierpinski's triangle for lack of anything else to talk about, and since me and a couple friends knew this stuff from a long time ago, we pulled out our calcs to play some games.  my teacher knew we liked calcs but he thought we were going to make a program to view it on-calc.  he said it wasn't possible, ;) so that made me want to make one.  by the time class was out, I had a BASIC (made by my friend) and an Axe version to wave in his face.  :P  but don't get me wrong, I like my math teacher.  ;D

anyway, so here are some screenies plus the programs

Serpnski is Axe
Axeserpnski is the source
and Srpenski is BASIC

it was funny how the Axe one was upside-down and I didn't bother to change that so I could flip my calc and have it shown right side up to him when I stood facing him.  (sorry for the weird wording.  :P)

Nice. I hope your math teacher was impressed by this xD

there is?

wow, I just took the Basic version from my friend and ported it to Axe, but then again he keeps that thing everywhere he goes

btw, I never got a Manual with my calc, just a user guide. ???

EDIT:  why does my post have a scroll bar?

Maybe its the user guide. It has 2 example progs in it and has most of the catalog listed and explained near the end of it.

IDK though. I tried the example program for the triangle and either i did something wrong or it doesnt work. Or its just extremrly slow and inefficient lol

EDIT: Heres a pic of the book:

no, the user guide has nothing about programming, only the manual, which I first read online.

thats what Axe is for  :P

EDIT:  yeah, I only have a really thin one that teaches you how to turn the calc on and off and basic graphing  :P

It's just really inefficient. That was the first program I ever tried and it took me a few tries to realize that I needed to leave the calc for a few hours. Being that slow, it almost put me off of programming.

Yeah and once its done, it doesnt even look that good.  I made a much faster, much nicer version of my own once i did some research into the Sierpinski triangle ^-^

wait, so it doesn't generate dots as it goes?
TI really sucks at coding their own calcs.  :P

I guess my friend didn't get it off his bring-everywhere manual then.  :P

nah, I was asking whether it did or not, since Broseph Radson said it didn't do anything, I thought maybe it displayed all the dots after an hour.

Just thinking about it, you could easily generate the same image a hundred times as fast just with the pxl-On() and Line() commands.
