Hi.
« on: April 06, 2012, 03:05:56 pm »
Hello. I'm TheNlightenedOne. I discovered this community around mid February of 2012 (via Google search). I joined in early March, but I forgot to post here. I have to say I really enjoy it here.
I'm a huge math, calculator, and computer geek. I currently own a TI-30XIIS, a TI-84+SE, and a TI-Nspire CX CAS. I know TI-BASIC, am learning C, and I plan to learn Lua and ASM (Z80 and ARM) over the summer. I have coded some things on my calculators, like a Pythagorean Theorem solver (TI-BASIC, for the TI-84) and a Fibonacci number generator (TI-BASIC, for the TI-Nspire). While I have only one post, I do browse Omnimaga often. I'm currently working on a TI-84/83 program for my teacher so that they can keep gradebooks on their graphing calculators. My next project is either a game for the TI-Nspire or perhaps a USB mass storage app for the TI-Nspire. I have a friend who also likes math and calculators, and I plan to get him on Omnimaga soon  ;D.
So now that you know a little about me, you'll see me around more.

Hi! Welcome to Omnimaga :D
Are "Eris" and "Aurora" the name of your calcs ? I like those names :)
See my profile (click on my name) to see what names I gave to my calcs and let me know what you think (I also "own" a TI 76.fr that never arrived and that I called Lulii).

And of course, have some more peanuts

Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

Xeda112358: That's actually extremely cool, I didn't expect anyone to be that near me. Also, are the numbers in your username a reference to the Fibonacci series?
Hayleia: Hey, your calculators have cool names too! Although it's disappointing that you didn't get your TI-76.fr...

Everybody is making me hungry for peanuts!

Yes it is in reference o.o I do rather enjoy the sequence :D I was glad to note that you made a program for it, but I was wondering if you were using the recursive form or the closed form...
(the closed form is a function where you input n and it returns the nth Fibonacci number).

Xeda112358, it's recursive form, but it would be a good idea to add closed form...

Here is an example!
Code: [Select]
round(((sqrt(5)+1)/2)^Ans/sqrt(5),0
That takes a value in Ans (should be an integer) and uses that to find the nth number. For example, 13 returns 233 :)

Thanks for the algorithm, Xeda. I'll work that in later today...

Cool :D it is really just rounding phin/sqrt(5) where phi is the golden ration.

Again, thanks a lot.
It's funny; whenever I talk about the Fibonacci sequence at school, everybody looks at me like I'm crazy... oh well.

XD That's okay, once you make it to higher level math, you'll meet more people who love math :)

I hope so... my math-enthusiast friend and I are both a year ahead in math. We're (or at least I am...) thinking about learning another year of math over the summer and taking the Regents in August.
