*this is just a joke

Because I'd rather pay a company that pays taxes to improve my own country's roads/education system/etc rather than paying some Korean company

>>9482721
Because we can't use phones during tests. What the fuck else can you use

>>9482748
Apple has an Irish holding company with no operations or employees at the top of its foreign operations. This company also serves as a group finance company. Apple Inc., the U.S. parent of the whole group, pays U.S. tax on the investment earnings of this company. Otherwise, the holding company pays no tax to any government, and has not paid tax for five years. It claims tax residence nowhere.

>>9482721
>Why does the American education system still rely on Texas Instruments?
Leftists in education and graft/corruption. They stuck a deal with McGraw Hill, Pearson, etc to integrate the TI calculators into textbook instructions and lesson plans.

>>9482887
And that's another reason I don't use apple products.
Although, they are bringing a large amount of that money back into the united states, where it will be taxed, just much less under the Republican's new tax law (36 mil as opposed to 81 mil)

mom's a teacher and she said apparently every major player in the education industry can be connected to george w bush in some way

never bothered to verify that so have a grain of salt

>>9482721
German here. My school uses Texas Instruments too.

aaaand it's trash

ti 36xpro is the best calculator you can get though.

Fuck, I haven't used a calculator more complex than my phone or simpler than Matlab in years.
I'm slowly becoming an engineer.

Fuck off /pol/.

>>9483906
statism is inherently leftist.

Just use your phone, it's more powerful than any calculator. It's not 1988.

>>9483189
this one thousand times over

>>9483973
Making sure your business is the top business isn't Satanism.

>>9483995
its not as fluid to use as a calculator.

>>9482724
get out you fucking ribbitor

do higher level mech engineering require a ti89 or inspire/cas calculator or is a ti 36xpro good enough? i really don't want to buy 1990 tech at $150.

>>9484505
*mech engineering classes

It sounds pretty obvious federal school board education just encourages monopolies for tests (SATs), calculators, and text books.

>>9482887

So in other words Laffer was right again?

>>9484059

Doing it thru the state is

It's certainly not the free market

Once again government interference holds us back

>>9484566

Effectively,

Higher tax rates just mean the big players will move away as they always can and now you're just fucking over small and medium sized businesses and making them pay gibs

>>9484576
anon, you can't just reply to yourself like that, you need to to add an asterisk so it doesn't look like you're samefagging.

>>9482721
It may feel bad buying an expensive calculator right now but TI was essentially responsible for your entire electronic life because they invented the first silicon transistor and the integrated circuit.

The calculators they are famous for were originally a meme product made to advertise their two big inventions and became popular because they were fucking useful.

>>9484895
You mean ordinary scientific calculators?

>>9484895
i like collecting calculators though. /g/ has their watch threads so i think we should have calculator threads. also what type of watch is the go to watch for mech engineers?

>>9484937
Digital casio in black

>>9484918
>>9484937
This was their first calculator.

>>9484943
What the fuck does p do?

>>9484844
>look like he's samefagging
He is objectively samefagging. Embarrassingly so, actually.

>>9484939
you mean the osama bin laden watch?

>>9484966
Casio has a few dozen watches that are basically identical and only vary in water resistance/proof/depth rating
I'm talking about the normal $10 digital casio.

>>9484981
tiny watches seem feminine though. i prefer a "meaty" looking nerd watch. I have a seiko and orient but those are stainless steel.

>>9484955
It prints out the answer probably.

>>9484985
Mate, hard edges are inherently masculine.

>>9485001

>>9485019
A circle does not have a hard edge.

>>9485028
Hard edges are a measure of contrast not shape.

>>9485133
Pray tell, what contrast is there for a sphere?

>>9485198
are Khazar milkers spheres?

>>9484572
>free market
doesn't work
statism doesn't have a left-right distinction, and in most cases, statists are rightists.

>>9482721
This is really a scandal. We ought to be introducing kids to math packages like Mathematica or even MATLAB much earlier in life, using crippled technology gives them a very distorted view of modern mathematics

>>9483037
Is that because of no child left behind??

>>9485693
The emphasis on raw and pure calculuation exclusively gives kids an even more distorted view than the calculators. Almost 0 computation is done after a certain point if you decide to study math which turns out to be interesting and fun as opposed to monotonous and mind numbing.

>>9485627
>and in most cases, statists are rightists.
Are you familiar with communists, socialists, and everything in between? You know, those inherently leftist things?
Because pretty much everything else that is statist is a literal monarch or dictator.

You could make an argument for dictatorships, you would be wrong. In order to make that argument with even a possibility of winning, you would have to stack the deck by ignoring every communist/socialist/marxist dictator because " they don't count ;) ".

>>9485693
>MATLAB
>using crippled technology gives them a very distorted view of modern mathematics
And yet you advocate matlab?

>>9486526
>Almost 0 computation is done after a certain point if you decide to study math which turns out to be interesting and fun
you filthy bourbakian

>>9485627
>statists are rightists

>>9484142
Can it differentiate, evaluate definite integrals, interpret summation notation, graph in 3D with multiple variables and, after a little fiddling, find roots for differential equations?

>>9486741
yes

>TI has monopoly
>still won't update hardware despite easily gaining all money spent on R&D back 10 fold
Just fucking update the TI89 already.

>>9483189
Hell yes. I still use a TI 83 for graphing stuff on exams when needed, but the TI 36X Pro is god tier for everything else, and it's only $20 something dollars. I definitely do not miss typing integrals in to the 83 when checking answers.

>>9487332
the new casio 991ex is probably better for vectors because it gives you the unit vector and angles between 2 vectors as an option. it saves time so you don;t have to do it yourself.

>>9487322
Just buy the nspire. It's like $20 more and better in every way, provided you don't want/need to program.

>>9482771
We use our big boi brains

>>9483906
>Implying he's wrong

>>9484989
kek i have one like this from casio

>>9485627
>statists are rightists
kek this trigger te ancuck, but this is objectively true. All the kigdoms were statists and certainly NOT lefties, actually ancucks are.

>>9484508

See >>9483272

I'd get the 36. And for serious stuff, download Octave. Its open source and understands all the matlab commands. So you are ready to go when you drop $50 on a student copy of matlab. Because everyone uses matlab. Even though it sucks.

Graphing calculators are a high school meme. In undergrad land, they are good for matricies, but otherwise exist in a useless middle ground of a no-mans land. Use Wolfram Alpha for that.

>>9483272
>more complex than my phone
do you own a nokia brick from the 90s? smartphone calc apps can do more complex shit than any graphing calculator.

>>9484955

>>9489680
In my mind, phones still can't get email.

>>9483203
I like the TI-30X IIS features and layout, but fuck this thing. It can't keep up with my key presses. If you don't release completely before your next key press, it doesn't register.

>>9489680
What can they do that a TI-89 can't?

>>9482721
They don't mess with Texas.

>>9489680

anyone who needs a fancy graphing calculator can use the one they have leftover from school rather than paying $5 for one on an app store (that will still probably be slow as shit and have no memory functions)

I have an HP prime, am I a special little snow flakeee
Cum cum play with my touch screen

>>9490544
>not using a GPD Win 2 as an overpriced calculator
Can you believe this guy?

>>9482721
cuz that shit does the work for you so you don't have to learn y=mx+b

>>9484142
also runs on 4 AA batteries

>>9482721
They work well and extremely reliable. i have two, a TI-83 and an nspire CX CAS

>>9482721
Saying "the American education system" is like saying "the Balkan government".

Just use geogebra on your laptop.
