That should be fine.

I have an old Ti-92+
Does the job fucking well, absolutely recommendable

Pic related, does everything I could possibly need, super reliable

>>5201043
that's why it's so fucking great

>how do I into significant digits- rounding?
RTFM

>>5201046
I have the 300MS version and I am in the same boat as you. Had mine since the beginning of High School.

>>5201005
Anything that does the basic "scientific" functions is completely fine. Graphing calculators almost always (but not always) useless for an engineering student because a real computer is way better when you need to do some machine graphing.

I have four Casio beauties: fx-82ES, fx-115MS, fx-570ES and fx-991ES. The ES models have a "natural display" mode that shows "textbook-formatted" input and output, but is suboptimal to use. All models have a "table" functionality that outputs the value of a user-specified function at equispaced points (useful). The latter three models have numerical quadrature (Gauss-Kronrod) and differentiation, but the quadrature is slow to the point of being utterly useless.

I've been using pic related for 6 years. I like it because it's easy to use. It may not have storage capabilities but I can still crunch numbers really fast with it.

Virtually everyone uses pic related instead, but if you're an Engineer and don't give a shit about preserving irrational numbers what you already have or what (>>5201046) suggests will be fine too.

>>5201043
>b-b-but it's wapanese

Because Japanese electronics are boss. I don't know why Americans all use those overpriced crappy Texas Instruments. Everyone in the rest of the world uses Casio. (UK here)

Yours will do, this is god tier though.

This >>5201168 is a WAAAAAY better calculator than >>5201046

>tfw you will never own pic related

Find out what the most advanced calculator you're allowed to use on tests is, and buy that one.

Other than that, a calculator you can't bring to a test is worthless. Go pirate mathematica or matlab.

>>5201241
Oh sweet lord. I just got a huge fucking boner.

This is what God-tier looks like.

1st year as well, TI89 was required

>>5201274
Sit down and be quiet when grownups are talking, kid

85MS was my highschool calculator...
oh sweet memories. The keys rubbed off but I can still remember the functions.

>>5201274
God tier indeed. 4 years of EE through this.

>pic related: this is my calculator now.

>>5201289
Man those old Casios are beautiful. I wonder why every brand makes these shitty plastic modern styled ones.

>>5201289
My dick is so hard right now. If I ever bought one of these, I'll have a boner 24/7

>Casio that can integrate differentiate and handle complex numbers

Those are banned at my university. I think they were technically banned at school exams too but no-one ever checked. (At uni they check your calculator model against a list if it's anything other than the common or garden casio everyone uses).

>>5201549
By the time it finishes integrating, the exam is over.

My school only let's us use pic related on tests, so that no one gets an advantage....

It's a pain in the ass to crunch large equations in this thing, are all engineering schools like this? (at university, not cc)

>>5201569
untruth

>>5201585
Perhaps that was a bit of a dramatisation, but the fx-991ES PLUS must be way faster than the "plain" fx-991ES to be tolerable. My fx-991ES is awfully slow at integrating anything that is not baby-skin smooth. I just tested it and it took 20 seconds to integrate sqrt(x) between 0 and 1.

>>5201585
>20 seconds to integrate sqrt(x) between 0 and 1
Oh shit nigger. You are better off doing it by yourself :P

>>5201614
Integrating sqrt(x) is still a pain in the ass on the plus.

>>5201614
>>5201633
this
>>5201622

Why the fuck would you use a calculator for that? It's babby level calculus that you can do manually.

>>5201643
The point was this: uninteresting stuff can be done faster by hand. Interesting stuff is a no-go with this calculator.

>>5201653
Actually you can use it to calculate complicated integrals that are a pain in the butt to do by yourself.

God tier calculator

Ti Nspire CX CAS

Best calculator i've ever owned, this shit is fucking DOPE!

(Electrical Engineer / Computer Science)

physics gradfag here

haven't used calculators on tests since freshman year of undergrad, luckily they don't ask stupid numerical questions in physics most of the time, so well-reasoned approximations are my best tool on tests

>for hw, pic related

>>5201726
friend of mine had this, jesus christ its amazing

>>5201726
That's overkill.
I bet you could buy a smartphone for less money and install an app that can do anything this thing can do.

>>5201804
Obviously overkill, but working on a smartphone is akin to torture.

>>5201804

Probably, but this big bitch is allowed on all the tests!

It truly is epic

>>5201726
got this one for birthday, even after saying I really didnt need it

gathering dust right now, except for exams, due to >>5201774


(physicist here)

>>5201726
Holy shit this must go for like $300

>>5201726
This is kinda ridiculous. The handheld calculator is a 50+ year old concept. Calculators are pretty much obsolete now that everybody uses MATLAB. Similarly drafting by hand is obsolete now that we have AutoCAD and SolidWorks.

>>5201812
Well, I've used a couple apps on Windows Mobile that were really powerful and user- friendly.

>>5201848
But what about the pleasure of pressing real buttons?

>>5201289
Oh man that's beautiful. Ultimate geek gear.

>>5201869
I bet that thing has a touch screen as well.
>>5201726

>>5201876
alas no, it doesn't have a touchscreen :(

but that big square button at the top is actually a touchpad mouse like on a laptop, as well as a big button / directional pad

the whole display is backlit as well

>>5201274

Best calculator ever, everyone should own this. Means you can check your work and move on to the next question confidently, no wasting time checking for errors by hand.

laptop every year

>>5201712
>no built-in CAS features
You mean useless tier? Even a TI-83 can do anything that can, sans the coloured screen.

I just use a Ti30. My university doesn't allow non-approved FE exam calculators in any of the classes.

Anything complicated just gets thrown in matlab.

>>5201948

there's 2 versions of >>5201726

the CX doesn't have a CAS
but the CX CAS does!

What are /sci/s thoughts on the Ti-83?
I'm rocking the + right now.

>>5202006

>>5202006
Do you even lift?

>>5202006
Rock solid drop-down-the-stairs durability, programmable in TI-Basic, C and ASM with a computer. Makes a good platform for introducing students to programming, IMO. It's slow when it comes to fancy graphs or integration, but it's still pretty good.

Casios have faster and more features for cheap, on the other hand.

It's great if you don't need a CAS. If comparing apples to oranges, then CAS calculators like the HP 50g, TI-89 or Nspire CX CAS mentioned above rock the socks off of the 83+. They're expensive as hell and it'd be better to Just use a laptop with some math software.

>>5201274
Close, but you're missing some functions of the fx-115ES Plus. No point in choosing the angel tier when you can have the true God-tier.

Seriously, having pre-ans and ans is so great.

>>5201168
fucking this. I've been using the same one since my freshman year of highschool.

>>5201168
>Americans

>>5201168
America has taught them that expensive = better. It's a sad relation to have as a society...

>>5201168
This.

>paying $100 for a decade old Ti-eighty shit.

BCUZ ITS MADE IN 'MURICAH
o wait it's made in china loltubad

>>5202174
What languages can you use to program it?

>>5202174
Nice backlight. How much did it cost?

I think >>5201274 is ideal, it does everything you could possibly want when you don't have access to your computer. I don't see the point of buying something more expensive just so you can program on that instead of your laptop.

>>5202200
I paid $60

>>5202174
>2011
wat

>>5202208
Only? I'm getting one.

>>5202192
It has a built-in BASIC interpreter, and it's programmable using a C SDK.

>>5202174
24/13 doesn't appear to be right, right!?
I get 1.999942187 which nowhere near 24/13

Use Fx 911ES Plus.

You're in degrees, silly. Switch to radians.

phew, disaster averted
