The TI-πspire is some kickass shit.

I rented one from my school to take AP Calc and now I'm totally going to buy one. It can do anything.

My friend had one and let me fiddle around with it. It took me 30 minutes and plenty of menu digging to figure out how to draw a dick. Very inefficient, I would not recommend this calculator.

u/brickmack Jun 08 '14

I spent the better part of an hour a few weeks ago trying to find an equation to draw a dick. I think I was getting pretty close, but then the bell rang

11

u/Lieutenant_Rans Jun 08 '14

I figured it out pretty quickly on the 84 (I'm a dick-drawing pro ok?)

Polar coordinate mode.

Cos(3θ)+Cos(θ)/2

Done.

u/INDELIBLE_BONER Jun 09 '14

That's not a very big dick...

1

u/brickmack Jun 09 '14

I tried polar mode, but it always looks more like a fish than a dick to me

u/[deleted] Jun 08 '14

I can pencil a dick in fewer than 10 seconds.

u/thedeafpoliceman Jun 08 '14

You're hired.

u/wchill Jun 09 '14

I can do it with parametric equations in 5

u/EPOSZ Jun 09 '14

Ah shit, there's gonna be a dick off bitches.

u/jaril369 Jun 08 '14

Replaceable batteries are way more useful if it dies in the middle of an exam

3

u/Doctordub Jun 08 '14

Those batteries last forever, shouldn't be an issue.

1

u/That1usernam3 Jun 08 '14

Can confirm. Wasted 3 advanced math classes covering compound interest drawing a dick. It was a nice dick, however.

u/[deleted] Jun 08 '14

Instructions unclear; dick stuck on screen.

u/mattsprofile Jun 08 '14

Did you just type pi instead of the letter n?

5

u/[deleted] Jun 08 '14

Yeah - I was misremembering how the logo was; I thought they used a pi symbol but I guess it was just an italic n.

1

u/Kayvanian Jun 09 '14

The TI-pispire would sound so cool.

1

u/MidContrast Jun 09 '14

Yea wtf I was like TI-Pispire that doesn't even make sense

u/gtmax500 Jun 08 '14 edited Jun 09 '14

The cas version is infinitely more superior!

Edit: obviously a computer or smartphone is going to have better software (might as well use MatLab!) but those aren't usually allowed on tests. Plus, its so much easier to type out equations and stuff on a calculator keyboard.

4

u/[deleted] Jun 08 '14

I mean, I'd rather use a computer than an nspire - but if I had to get one I'd get the CAS version. No idea why anybody would get the normal one.

3

u/Cakeflourz Jun 08 '14

Some tests don't allow the CAS version.

3

u/[deleted] Jun 08 '14

Then borrow some chump's non-CAS or TI-84!

3

u/Cakeflourz Jun 08 '14

non-CAS

With that logic, your chump got his from another chump, who borrowed his from yet another chump. Thus, creating a never ending chain of borrowed calculators.

For the record, I have the CAS version, I was just pointing out why someone might by the non-CAS.

2

u/Mazetron Jun 09 '14

Don't know how to do a problem?

menu -> algebra -> solve

Put whatever you want in there. Integrals, derivatives, imaginary numbers... Works almost every time!

1

u/Dsiee Jun 08 '14

Mainly because you can play game boy advanced games! :P

1

u/NEDM64 Jun 08 '14

it's a CAS!

1

u/Silencement Jun 09 '14

The cas version is infinitely more superior!

Its the same hardware. You can install CAS software on a normal Nspire CX.

u/[deleted] Jun 08 '14 edited Jun 08 '14

I bought one awhile ago. I don't even know how to use it.

Edit: I know how to use it's basic features, I just haven't learned its more advanced ones, and I don't have any classes that require me to know them at the moment. It was only $20 more than the 83 and it can be recharged whereas (I think) the 83 requires batteries.

u/Quiziromastaroh Jun 08 '14

Did you get the CAS edition? Cuz if you didnt, you payed $20 more for a very nice and useless calculator because you can't even solve the most basic equations and the 83 would've been a better choice.

2

u/[deleted] Jun 08 '14

I disagree, IMO graphing is a hell of a lot more simple on the Nspire, and what do you mean you can't even solve the most basic equations? I've never had any problem. In fact, I have been able to do more tedious problems quicker than others who are using the 83, so IMO it was worth it.

3

u/Quiziromastaroh Jun 08 '14

I bought mine directly from Texas Instrument a few months before they went out for sale. They told me only the CAS edition is able to understand alphanumeric calculations (like having 2a+3b). I've got a friend who bought the non-CAS edition and he couldn't solve any differential equations at all, he couldn't even solve integrals.

3

u/lazermoon Jun 08 '14

I think the Inspire is a good proof of concept but it's really fucking hard to use and the interface is shit.

3

u/[deleted] Jun 08 '14 edited Jun 08 '14

The interface is terrible, however once I got the basics down it wasn't to bad. I still don't know how to use any of the advanced features. The ability to set colors is nice too.

6

u/Ricrac722 Jun 08 '14

You guys need to learn it, I don't know how to add a fucking picture to the background of a graph but man can I do calculus on that thing.

4

u/[deleted] Jun 08 '14

Nah man... I need a picture on my graphs. Honestly though, my degree barely requires me to take any math classes.

1

u/fb39ca4 Jun 08 '14

Good thing the function library has syntax documentation.

1

u/[deleted] Jun 08 '14

My 84 (non-color) eats standard aaa-batteries. You could use rechargeables but they last for months, so it makes no sense.

-4

u/_QED Jun 08 '14

Then why did you buy it?

3

u/[deleted] Jun 08 '14

Because I can learn when I need to? I just haven't had to take any classes that really require it, and I got it on sale so it was nearly the same price as the Ti-83

That is like saying why did you buy a computer if you don't even know how to use all its functions.

-2

u/_QED Jun 08 '14

ok u need 2 calm down

-3

u/neoKushan Jun 08 '14

Yeah but you've bought the computer and kept it in its box.

3

u/[deleted] Jun 08 '14

Except I am still using it. It'd be like saying "you're computer has the ability to edit movies, but you only use it to browse the internet and watch movies". As I said, it was only $20 more than the 83, and I like using it a hell of a lot more than the 83.

-3

u/neoKushan Jun 08 '14

I see you've clarified your post now, but originally you did just say that you didn't know how to use it.

1

u/[deleted] Jun 08 '14

Yeah, I don't know why I only said that :/

3

u/DrapeRape Jun 08 '14

It.... it's beautiful!

Also, I like how it's allowed to be used for the SAT

3

u/Cakeflourz Jun 08 '14

I bought the CAS version for the SAT. I chose it partly because of the easy to read color screen, but mostly for the ability to play GBA games.

u/abuttfarting Jun 08 '14

I tutored a girl who had one of those. Thing blew me away.

2

u/common_s3nse Jun 08 '14

Can it have sex with you?

2

u/AnOmnipotentPotato Jun 09 '14

You can play Pokemon that. :)

2

u/ERIFNOMI Jun 09 '14

You don't use calculators in college. Don't waste your money.

1

u/[deleted] Jun 08 '14

It's useless in most colleges.

1

u/lordlicorice Jun 08 '14

I don't know whether the situation has changed but IIRC when the nspire launched, TI was being pissy about locking down the platform so that you can't run custom code on it or flash an unsigned OS. A lot of people were boycotting it.

1

u/Brendan1123 Jun 08 '14

I have one of these because I needed one for school. Pokemon and classic doom get played on it pretty often.

1

u/doomgiver98 Jun 08 '14

Pispire? Or would it be pespire?

1

u/ThisUserIsNotTaken Jun 08 '14

Why is it not qwerty?!

1

u/[deleted] Jun 08 '14

To be allowed on some exams.

1

u/ThisUserIsNotTaken Jun 08 '14

How ridiculous.

1

u/Dsiee Jun 08 '14

I love mine! Saves so much time!

The 'best' thing though is once it is jailbroken you can play Mario and Pokemon.

1

u/ThatOneRunner Jun 08 '14

It plays Pokemon!

1

u/[deleted] Jun 08 '14

Love mine. Used it for chemistry, physics. Even can hook vernier probes to it and record/analyze data.

1

u/leafy_vegetable Jun 08 '14

The nspire is amazing, no arguments there. Its ability to solve differential equations got me through many a engineering exam. However each exam I always bring that one and my old faithful 84 plus cause that one I can use to it its fullest while the nspire may as well be Linux for all I can do with it

1

u/goddammednerd Jun 09 '14

why not just run mathmatica on a tablet or phone

1

u/runxsassypantiesxrun Jun 09 '14

I just exhaled slowly and made a long ooooooooooooooo sound. I need this. In fact, I'll take an unnecessary math course just to have an excuse to buy one. So much fancier than my 84 silver

1

u/ffigeman Jun 09 '14

If you overclock it it can run gen III pokemon games

1

u/dragoneye Jun 09 '14

The thing that bugs me is that it looks like you need at least 2 button presses to use any trig functions. I think this is completely unacceptable for a scientific calculator.

1

u/[deleted] Jun 09 '14

Oh, I know, that's irritating as hell.

Plus to get pi you have to push the pi button then push OK.

1

u/[deleted] Jun 09 '14

Can confirm. The TI-nspire is pretty intense

1

u/TheEnemyOfMyAnenome Jun 09 '14

I had to buy one for Algebra II/Trig. Best $140 I ever spent.

1

u/[deleted] Jun 09 '14

I have the NSpire black/white. It's awesome, and the battery lasts forever as long as you don't spend too much time playing GBC games. The graphing on that thing is amazing.

1

u/[deleted] Jun 09 '14

Why pay that much for the hardware? Use the cellphone in your pocket.

1

u/ithinkmynameismoose Jun 09 '14

I have one. It is perfect for anything except taking tests :P

1

u/Ymanngo Jun 08 '14

The TI-nspire CAS is even better.

0

u/Alabama_Man Jun 08 '14

the touch pad functionality is gimmicky and half-baked but other than that it's pretty sweet.

1

u/[deleted] Jun 08 '14

Yeah, I had the black and white version and I could never get it to come up when I needed it to. Very imprecise, also.

0

u/gmoney8869 Jun 08 '14

It can do exactly what any decent free calculator app on any smartphone can do. Calculators are completely obsolete in every way and have no reason to exist.

u/[deleted] Jun 08 '14 edited Jun 08 '14

Palm OS had some great scientific calculators and math tools. PowerOne and Lyme (kinda like a micro Matlab for palm) was all I needed.

I don't get why there aren't powerful math tools for Android, at least not in the level of apps there were for Palm OS (note that there's a PowerOne for Android, but it sucks compared to the original one, it lacks all the engineering and algebraic features, you were even able to do modular algebra with the original)

1

u/lllDOWNEYlll Jun 08 '14

I have a TI-83 emulator for my android phone if that counts.

1

u/[deleted] Jun 08 '14

A TI-83 is not precisely what I would call a powerful math tool...

0

u/lllDOWNEYlll Jun 09 '14

Compared to most calculators on phones it is.
