What calculator does /sci/ use?

I have a TI 30XIIS, but the buttons on it are horrible.

>>	Anonymous Sat Oct 29 21:40:18 2016 No.8445257 Ah, the good old days... I rarely get to use a calculator anymore. When I do it's either a TI 36X or TI-NSpire CAS.

It has all the physical and astronomical constants you'll ever need, and you can instantly copy results from a previous line of calculation into the next, not to mention having extensive 2D graphing abilities. It also has a reference section if you can't remember the cosine rule or whatever. Also included are a triangle solver, third order polynomial solver, and a matrix calculator for the more lazy of us. You can't bring it into an exam of course.

Does everything. I have used the graphing and regression functions a lot in the real world on the job. The Statistical functions for data analysis are nice too.

Switched to Excel in the office mostly for work but when in the field the good old TI-83+ does everything.

Bought this thing in 2000 during highschool and have had to replace it once.

calculators are the biggest fucking meme in the world. These things are literally worthless 1970's piece of technology, yet they force kids to fork out $$$ to buy something that has literally $0 tangible value. Your phone is a fucking super computer compared to these things why do they still exist, it makes me so fucking mad.

also stop using calculators and use your brain, there is no reason why you would need to use a calculator to learn any mathematics that isn't super applied, and by that stage you should be using actual computer packages.

Suppose you want to add interest to something.
Are you really going to use a computer software package to compute 1.044^23? That's pointless.

Calculators are meant for these kinds of intermediate-level computations that are trivial to do for a computer but are prohibitive to do by hand.

>lol, bullshit.
Objectively, pretty much every CPU used in smartphones is many, many times faster than what you can buy in calculators.

>there isn't a single calculator phone app with a decent computer algebra system.
There's plenty available actually, I doubt you tried every single one of them. Also, most CAS I've used on calculators suck pretty bad as well, especially because you are running them on a fucking potato. Everything works nicely as long as all you do is integrating polynomials, but once you want to move to more complicated things the thing gets a stroke and you are stuck. Software available on computers, e.g. Mathematica, Maxima, Maple is so much more powerful, especially because there's a number of packages available that help you with the stuff where CAS are actually helpful or even essential, e.g. calculating matrix elements in QFTs.

>>8450611
And you shouldn't be. It's useless and it's damaging your intuition. Looking at a function you should be capable to imagine what it looks like.
