It seems like this is an April fools joke.
Anyway, a quadratic equation solver is the easiest thing to make; however, i don't need to make one for my ti-89.
I wonder how people without a ti-83 plus would make a quadratic program.

With a genetic algorithm? It's not like there aren't enough "genes" already in the archive... :p

That's a shame! I wrote a virtual memory, real-time, preemptive multitasking, multi-user OS for the 89 and 92+. I can't for the life of me figure out how to write an original quadratic solver, though, so I can't submit my OS. I guess I'll just erase it and go back to playing minesweeper.

Oh, who needs new OSes, honestly? We have about 9001 of those. What we really need is more quadratic equation solvers, which is why I wholeheartedly back this effort ;)

The joke itself isn't the best we've ever seen, but some of the comments here are pretty funny.
Pity I don't get to play with calcs anymore... :( I only visited today because I was curious about the April Fools joke. Shame on me...

Hey, the article is not in a red border...
That's strange.

They only do that after April 1st, or after it's obvious to everyone that it's fake.

Now it's red. They usually change it the day after.

Are comments also required to carry a copy of the quadratic formula? ;-)

(-b+/-sqrt(b^2-4ac))/(2a)

I reject your notation and substitute my own.

$\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Kind of glad that this was fake news.
I imagine that there would be a limited number of ways to do a quadratic solver and still be 'original'.

I very much doubt that. I am pretty sure Rice's Theorem (see URL) would imply there are infinitely many implementations of any functionality, which can be as distinct as you care to specify.

On the other hand, most of these "original" quadratic solvers would probably be extraordinarily difficult to prove correct.

I know all about Rice's Theorem. It was my Uncle Ben who came up with it. It states that if you boil the rice too long, it gets sticky. I also shave with Occam's Razor and cut up my cabbage in accordance with Cole's Law.

I implied ones that can be programmed on an 83+ and/or perhaps on any graphing calculator; perhaps even on a computer.

Well, technically speaking, the TI83 only has about 27 kB of user-accessible RAM. Which means there are only 2^27000 (give or take) different programs possible. Not all of those will be quadratic solvers of course and even among the quad solvers, there will be ones which are not "original" (write a solver in 200 bytes, put a Stop command and you have 26.8 kB of junk space to play with) but it's impossible for more quadratic solvers to exist. So yes, there is definitely a maximum number of quad solvers which can exist.

HTH,
Rob

ps. Yes, I know that programs can also be smaller than 27 kB. However, sum ( 2^x, x, seq ( x, 1, n ) ) [I hope I remember TI-BASIC syntax correctly ;) ] equals 2^(n+1) - 1, which is well within the range of "give or take"!
