TI Z80 / Output in exact format
« on: October 14, 2015, 01:38:02 pm »
Is there any program for the 83+/84+/SE calcs out there to allow you to display the result in exact format for irrational numbers, such as sqrt(2) / 2 or pi / 2? (Like the TI-36X does it)

If not, is there some algorithm which allows such conversion? (might implement it then :3 )

This is sounding really awesome, can't wait for screenshots!

Thank you! Better late than never!
I built the tall tower together with a friend, we made modules and then lifted them on top. Ladders are quite helpful for that and the fact that it is actually standing partly on the balcony!

Can't wait for a demo! I still think that when moving fast the water is looking gray :P

Math and Science / Seemingly Complex Numbers Paradox
« on: October 02, 2015, 03:13:57 pm »
So, in uni with a few other students we had a seemingly paradox with complex numbers, but I think we solved it, wanted to share it with you guys anyways:
##i = e^{i\frac{\pi}{2}} = e^{\frac{1}{4}(2\pi i)} = (e^{2\pi i})^{\frac{1}{4}} = 1^{\frac{1}{4}} = 1##
On first and second glance this seems to be math-defying as ##i## is clearly not equal to ##1##. Below is the solution to this paradox we came up with.
Spoiler For Solution we came up with:
As ##i## clearly does not equal to ##1## there must be an issue here. We believe the issue to lie within the ##1^{\frac{1}{4}}##. As this is taking a root the answer is not unique, but there are actually multiple answers to ##1^{\frac{1}{4}}##.
Let me re-format that a bit to make it clear:
##
1^{\frac{1}{4}} = x \\
\sqrt[4]{1} = x \\
1 = x^{4}
##


From this point on it is quite obvious, there are multiple solutions to ##x##, that is ##1##, ##-1## and also ##i## and ##-i##.
So we have to say:
##
1^{\frac{1}{4}} = \{-1, 1, -i, i\}
##

So now clearly our real solution, ##i##, is present!
So yeah, just thought it would be fun to share :P

I am nowhere near xedas math skills, please forgive me

Yes, crossposting would be awesome! ^.^

I don't think there is TI-Boy for the CE out yet, but who knows what future will bring us!

Yeah, this sucks a lot :(
That is why, for my programming projects, I always use like bitbucket or github to back up, bitbucket for if I want a private repo.

Sounds awesome!
Any chance for a demo video? (maybe after/during the fair? :P)

TI-BASIC / Re: Collision Detection
« on: September 20, 2015, 02:19:07 pm »
For one there is a thing for TI-BASIC on tibasicdev over here: http://tibasicdev.wikidot.com/68k:83coders
But those calculators also have the newprog language (more powerful than TI-BASIC), which you can find (including documentation) here. http://www.ticalc.org/archives/files/fileinfo/426/42635.html

Oh crap, I think I just accidentally cleared my calc screen.....other than that, glad to have you back on board! Feel free to share any android-dev you are making!
Are you currently working on anything interesting?
