ITT: Preferred calculators, notebooks, pens/pencils, or other academic equipment.

>Just picked up this bad-boy

Can someone recommend a nice pen? Been using the Pilot G-2's for a long time, ready for a change/upgrade.

Anyone know of a non-graphing programmable calculator with a nice development environment?
>>
>>7815471
I've used that Casio quite a bit, quite nice. Haven't dicked around too much with complex numbers on my new one yet. At least it has a complex function, much better than my 10+ year old TI-83.

>not just using wolframalpha on your phone

I have had a Casio fx-991es since school and other than the missing number buffer, it's great. Later, I also got a TI-30 ECO RS, which is also okay. If you're not used to it, calculating complicating formulas can be a pain in the ass though.

>Preferred calculators
TI-89 Titanium or TI-30X Pro.

the 30X because its allowed on the FE and PE exams, and the 89 because the programming language is simple as fuck, but it still has a Computer Algebra System, so its like having a laggier matlab in your pocket. learn to write little apps in that mother fucker and you will wreck any engineering exam (provided the teacher allows them). I wrote FEA and CFD programs in that thing.

I'm a pretty heavy handed writer so I break .5 easy. Also I really like dark lines. It's like a pen Do note I use two or three lines on college ruled for an integral symbol like a disgusting pleb.

Try it on a good open source GUI calculator application. That way you can see the whole stack which helps you get the hang of how it works and see if it makes sense to you.

>>7815981
It is for the most part 'dead' - only a few calculators come with it and they're set to infix by default. I don't see why you care about an input method which you're not forced to use which some people might find more convenient. Like I did.

Not edgy or false in the least bit.
After a while calculators just become cumbersome. It's faster to do things yourself unless you're simulating or doing tons of algebra (which it seems like one rarely does).

Lately I've been doing my work with a surface pro pen. A paradox, considering my stance on calculators vs. pen and paper.

What's a good calculator for someone who is in an [spoiler]engineering program[/spoiler] pls don't meme me.

ti 89 titanium

if they dont let you use one of those, ti 36x pro as in the op.

ti is the only company that has intuitive calculator UI design down. theyre more user friendly than anything else out there.

HP 50g is more full-featured and arguably better for the one weird professional that still needs to use a calculator....

but literally no one uses it in school and you will be the only kid in your program suffering to debug some weird reverse-polish-notation you accidentally entered slightly wrong

ti 89 will do more than you will ever need

plus u can play mario on it
>>
>>7816499
I'd say that infix parenthesis-soup is more bug-prone than RPN.
>>
>>7816499
should I buy it new or refurbished?
>>
>>7816503

refurb

look on craigslist and student forums and university groups on facebook, ebay people make a racket on this type of stuff

expect to pay 40 to 60 bucks for a good deal on one in good condition

Best calculator coming through. I've been using this model since my sophomore year of high school. I'm a junior in mechanical engineering now.

I've never felt the need to own a graphing calculator, and I'm not allowed to use them on exams anyway.

Are you fucking retarded? It says complex numbers right under where it has derivatives and integr-- oh wait, yours doesn't have those :^)

>>7815483
Good calculator, it was my first graphics one. Used it in junior year of high school until I upgraded to this bad boy I've had ever since.

>judging but not posting a pic of your CAS to prove superiority

Had that too, personally prefer the Casio fx-82AU+ II for its display of fractions and ability to reduce a number to the product of primes (perfect for simplifying surds).

this is literally the only thing i used in undergrad for math b.s.

most of the time, calculators aren't even used for tests.

anything you can't do on that calculator, you do in mathematica/matlab

only use pens to write your shit. even on tests. using pencils encourages academic dishonesty as well as leaves no way for you trace your train of thought on failed problems

don't listen to /sci when it comes to calculators

graphing calculators are for faggots that think they can show off how smart/cool/techy/devoted to learning they are

just like in /v where people think fighting sticks are advantageous over gamepads

I'm sorry. Yeah they're good, the size of the buttons took me a while to get used to after the TI-84+ though.
