The gamma function is defined as this integral:

I can rebut the Gamma of 1/2 being sqrt(pi) argument.

You are able to reduce it to the area under the normal distribution, which we can figure out by squaring and rewriting in polar coordinates, which results in a factor of 2pi. The integration then cancels to leave a bare pi, which, again, is a coincidence.

And this is why I don't use τ:

And I'm hoping to change this

HOW?!?!?!?!??!? (did you get the char) That's awesome!

Just take the cakeiPhoenixJust take the cake now has 300 posts!

EDIT:
Also, if there's a war, I call Sweden or Switzerland. Preferably Switzerland. No offense, Swedes!

The token for Tau already exists on the calculator at 0xCC
I used TI Connect(TM) CE to make this program, using Char/Greek to find the τ symbol:

Code:

Then I used

Oh yeah. In (most of) my programs, I have a string with a bunch of chars you cannot get normally, and store it in str2. I then use sub() as necessary.

EDIT:

BREAKING NEWS MATEO CALLED PEOPLE WHO USE TAU "in need of higher math"

But that's not the worst of it! Jacobly then gave him karma! But who cares?! Not me....

EDIT EDIT:
*keeping it cuz it's funny and adds to the thread. Admins, I hope this doesn't add to my word count...

Lines starting in "*" mean my annotations. I was half asleep, ok?!

Quotes and code tags do not add to your word count. If I recall correctly, post edits do not affect your word count either. My source on that is when I delete a spam post, the account has 0 posts but 46 words or whatever the word count was.

Good! Thanks! I just don't want to take credit for words that aren't mine.

Tau when you want to say 2*pi.
Pi when you want to say tau/2.

Just use them interchangably when you want to get rid of a /2 or a *2. Problem solved.

Nah. There can ONLY BE ONE!!

jk lol.


P.S: Use degrees

Since nobody else will post about thisblame PT_ and Mateo

I will be explaining the progress of the 'tau integration' as I would like to call it.

After much pressure by JWinslow,srsly browork has started.

Basically, Mateo determined it was possible, and PT_ joined him (as in they were both doing it indepentantly) tried to come up with ways to make it happen.

The basic idea is evolving to this: find a way to make a tau char appear (for visuals) when you press the [π] button (instead of π), and either make pi evaluate to tau (2pi) or create a new token for it altogether.

If you have any ideas please post them.

I am still impartial, just posting as a "news" story.

Nice

Good job! and source code?

The name of the gif is tau.gif. Enjoy

pretty neat

Okay, here we go!

And the 83+ version? (For those of us too cheapskate to buy a CE)



EDIT:
One other thing you could do is add tau as a contant, like pi and e. I think this would require two hooks:

The first hook would output the tau token whenever a certain key combination (I was thinking [ALPHA][VARS] is triggered.

The second hook, a parser hook, would trigger whenever the tau token is evaluated, and return the numeric value 2pi.


Please let me know if I am thinking about this wrong.

Yep, this is wrong, because the parser hook won't run at the tau token. You can only trigger the parser hook by replace an existing token by the tau token, whereas that token needs to trigger the parser hook (not all tokens does). But now you get more problems, like, when is that token the token itself, or when is it tau?

Only problem with the current tau program:

Upon activating "tau mode", Disp, a Pause, and seq() return a syntax error for any arguments you give them, and ClrHome seems to stop program execution. Also, other problems I might or might not find later with how instructions are evaluated.

Fix?
