depending on your school you may need at TI-84 for statistics. Sometimes you get forced into taking a stats credit.

Real math doesn't need a calculator, but sharp makes decent ones for students that do a bunch.

>Hey /sci/ any of you guys know a good calculator that will carry me threw college in all fields

Any solar powered scientific. The FX 115es plus (aka fx991es+) is the most popular.

You will never need to or want to do that stuff with a calculator.

I've been using a TI-83 Plus Silver Edition since high school. Trying to make the switch from a graphing calculator to something a bit sleeker and with some built-in solvers: like quadratic and cubic. Anyone have suggestions?

>>7598411
Look everyone, someone who has never taken a science course requiring applied maths!

>>7597159

>>7598403
This tbh, but really what do you need a calculator for in college/uni. My physics classes all allow us to use one, but the equations can all be solved in your head due to the numbers used making it simple.

>>7598596
>something a bit sleeker
You mean something with less functionality than a graphing calculator, but still able to solve quadratics and cubics? >>7597847 will do that

>>7597167
A fellow truth seeker, I have found.

>>7597012
Use of calculators is only permitted in my physics class but even in that class I have a limited selection of calculator brands that I can take into exams. Also, in my linear algebra course, calculators are banned. Fuck me man.

>>7597167
>Graphing calculator with no visual graphing

>>7597012
Any scientific calculator will do. You won't be allowed calculators on tests. You should get in the habit of not using them. If you need a calculator, you can find an emulator online. Don't buy one.

>>7599682
>You won't be allowed calculators on tests
Everywhere I've been, it was entirely up to the professor.

>>7597012
Voyage 200 this baby does everything

>>7599682
I agree with the philosophy, but most professors let you use a nongraphing calc

>>7598596
I have the same calculator

HP 50g. RPN / RPL is the best. There is a huge library of programs which will do basically anything you need already, it is easy to program, and it has everything. This is a calculator for a scientist or an engineer.

Yes, obviously you might want a computer program or two as well but nothing beats a good calculator for number crunching.

Here, watch an old HP 41 calculator control a plotter and plot a function.

TI-89 has worked good for me the past several years. Graphs, solves shit, does a bunch of other shit too.

>>7597159
Very easy to work with. Would recommend this too.

>>7597012
Any android device?

>>7600279
Toys like that lack real buttons and are therefore not suitable for directly replacing a calculator.

>>7600247
This. although you should get used to not being able to use a TI 89 exam time. That shit is so gnarly, it does everything.

TI 84 silver is my favorite
You can also get an android emu for it called wabbit but that obviously isn't allowed on tests

>>7597831
I have this too. Really fucking hard to use but it does literally everything.

>tfw you can only use TI calculators

What calculators do they let you children use on tests these days?

When I graduated high school, /pic related would have been the state of the art calculator.

>>7597831
You can't even properly program that thing you dumb nigger.

With an HP 50G you can program in RPL, Saturn assembly, and ARM assembly right on the calculator plus any language supported by GCC with a computer.

Seriously you kids.

Reminds me of a maddox piece: http://www.thebestpageintheuniverse.net/c.cgi?u=iphone

>The technology is called "tactile response," and it allows you to do things like dial a phone number without staring at your screen like a shit-chucking ape. In fact, every other cellphone ever made has this technology, sometimes called "buttons."

>>7601107
Oh my God I fucking loved my 89 but one day it froze up and became an $70 paper weight. I can't stand my 84 Plus now.

>>7597012
This cutie.

>>7601027
So why not just use a cheap laptop?

>>7601568
A calculator is much smaller and the batteries last much longer. It is always at hand. Also, being a dedicated math machine it typically isn't loaded with distractions. A good calculator can be programmed easily to tackle the task at hand. Many people still favor old-school keystroke programmable (closer to assembly code than anything) scientific calculators because it is really quick and easy to develop and implement an algorithm and then crunch some numbers.

RPN and / or RPL as you'll find on decent HP calculators is really excellent for crunching numbers, repeated calculations, and playing around with inputs to a function. Changing or using a previous result in TI land is clunky and it is impossible to do programatically. With RPN / RPL it is easy. Most of the time you don't even need to use variables - you just use the stack. Plus because HPs aren't neutered school calculators, you are free to write programs, hook lab equipment up to them for automation, and so on.

There's a reason why most of your top-tier nerds use HP calculators.

>paying for this shit

>>7601200
This is the best calculator ever made, bar none. It still pisses me off how HP rearranged the keyboard on >>7600242 shifting the /x-+ up in order to put the enter button in the bottom right corner. And the HP Prime is still a joke. Yes, I have all three.

>>7597831
I have the cx, I have to agree, it is GOAT. It has essentially everything you ever need out of a calculator, and is easy to use.

>>7601164

Curse out your school until they let you use a Casio.

>>7601849
The 50G's new keyboard layout sucks, but the case is much sturdier, the SD port is much better than the proprietary memory ports, it's faster, and so on.

But that damn key layout and glossy screen, arrgh.

Still I bought an extra 50G to put away for a rainy day, as they are being discontinued at the end of the year. They will be $250+ NIB soon like other older HP calcs that were never properly replaced.

>>7597847
I just bought this one. It's pretty cheap, comparatively. I miss some features, though.

>maximum matrix size is 3x3
>maximum linear equation solver is 3 variables
I'd be happy if I could solve a 5 or even 4 variables linear system. Matrix mode also doesn't have a eigeinvalues function, but I can do that by hand so it's just an annoyance, since it does solve cubic equations and the maximum matrix size is 3, you can even solve it using the calculator. The constants list could be more comprehensive, including astronomical constants such as sun's and earth's mass, radius distance, luminosity.
But this is what you get for 20 bucks.

>>7601807
GCC?

>>7601807
>supporting GNU/gommunism

no

HP 32II is the best calculator ever

I use the IT 30XS multi view for my science classes mostly because they won't let us use graphing ones. The IT 30XS multiview is wonderful it's easy to put formulas in it then scroll down and set constants as variables. There is also a pro version that my school doesn't know about that has the constants in it. Now my current math class we are not allowed to use a calculator but when I get to a class when I need one I'm going to be getting the Ti inspire.

Casio 9750GII

Got one in high school, and although a few have been stolen, I'm using it in third year EE. Unfortunately the math has gotten lame, so it's not as useful anymore. Used it for Calc 3, LinAlg, and DifEq

>TI calculators
>can't trace dy/dx unless you pay >$150
>defaults to "insert" behavior like keyboards
>Casio 9750GII
>dy/dx on every trace, easy to check derivatives
>adds characters by default
It's not something you think about, but say if you missed a parentheses, on TI it's second->insert->paren and you HAVE to be on the location already. With the Casio it's just move to the spot and hit paren. TI calculators are literally shit.

>>7598596
I been using this since 2005. never thought it would last this long.
