>>54024023
The textbook companies literally includes step-by-step instructions on how to 'solve' your problems in all the modern textbooks but only for current-gen TI calculators.
TI provides free 'training' for the teachers as well, which is really just a disguised sales pitch.
The sad thing is that TI's calcs are so damn limited and they use every trick they can to stop you from running your own code.
HP gives you on the 50g, built into the default firmware:
>MetaKernel, originally developed by a hacker later hired by HP
>RPL programming environment
>System RPL programming environment
>Saturn microprocessor assembly language development environment
>ARM assembly language development environment
Adding on other programming languages is easy and they can be extremely fast. I bought (yes BOUGHT!) Hrastprogrammer's BASIC. He develops a full line of FAST emulators for older HP calculators on the HP-48 series (written in assembly language), as well as an excellent BASIC which seems to be even faster than RPL for many things.
The HP-41 series has seen a recent refresh as well, the HP-41CL which is a brand new main board that carries a new FPGA-based SOC which is up to 100x faster, allows USB and serial communications, etc. which you can insert into your older HP-41. A CAS is being worked on.

Buy a Casio FX 9750 GII. I used one all throughout high school (starting uni next year) and it has never failed me. It's pretty ugly though, and you can't expect to be spoonfed by your textbooks, but if you're willing to figure stuff out it is generally accepted in standardized tests and what-have-you.

>they are essentially the first graphing calculators ever available on the market
Not true, the HP-28C beat them to the market and could graph functions though it was slower and had a very wider-screen format. You had to write a program to plot each pixel on the axes and you couldn't ride the curve like in a "real" graphing calculator but you could plot a function for sure.
It was never marketed as a graphing calculator though it was indeed in every way, a graphing calculator.
>>54027328
I feel sorry for today's children, they lack the tools we had even fifteen years ago.
But let's remember that HP invented the graphing calculator IN 1968! Yes you Casio tards, 1968.
Here, enjoy an HP-41 plotting a function over the HP-IL interface bus, which was also amenable to RS-232 devices.
This was in 1979, the HP-41 was also provided onboard the Space Shuttle as well as other craft (B-52, 747, et al) as a backup aviation / orbital computer. Later the HP-48 was adapted into this role.
You could plug it into the Space Shuttle and run the program and it could land the thing.

HP calculators aren't just calcs, anons. They are designed to be your best buddies, true pocket computers.
It's comfy.
>>54016001

It's true but RPN / RPL will always be the tops my dear anon.
Get with the program, you will have comfy calculating sessions ahead of you.
Pic related: one of the several modern HP clones I own, this one was designed by Steve Wozniak and re-implemented with original display chips but on one SoC and one FPGA.

Why even exist?
I've been needing a good calculator for a while, and after reading through this thread I am torn between the 48g and 50g.
Are there any specific advantages or disadvantages to each or is it just an older model vs a straight upgrade situation?
>>54029495
The 50g is a modern superset of the 48g, other than autism about the placement of the enter key, there is no reason to select the 48 series these days.
50g is not a meme calculator. Get one while they are still available and cheap at that.
It also has a bigger screen, is 3x faster, and can run off USB power even without batteries and takes an SD card rather than special unobtanium expansion cards limited to 4mb or so.
this is a program i made for the 50g that gets you critical points given a multivariable equation.

Surprised people aren't posting more high-end non-programmable calculators. Unless you go to a shit college, they won't let you use your precious graphing calculators for any reason whatsoever.

SwissMicros Swiss-made HP calculator clones are made of titanium or brass and are about 40x faster than the real deal.
You can switch them into a low-speed mode for enhanced battery life though.
Coincidentally, with shipping to the USA, they are about $150.

>>54031554
I have two SwissMicros but if I run across a 15c within my stingy budget I will snatch it up.
Some people are still running them on the original batteries they came with in the 1980s. Silicon on sapphire technology, very rare and now only used in satcomms and other high-dependability applications.
>>54031461
>>54031446
Casio has support for 9 variables.
Casio has built in functions for some useful equations. For instance I can set a=5,b=6,c=3 and the calculator will tell me that that x=-(3/5)+-(sqrt(6)/5)i.
It represents square roots up to ~9000 algebraically. If I input sqrt(20) it'll say 2*sqrt(5).
Has a 4 line display so you input more info at a time.
The complex mode automatically multiplies out the i, so if I did i(6i^2+5i-3) it'd simplify it to -5-9i, makes life much easier.
It just streamlines so much shit.

That's terrible, the HP-9100 introduced in 1968 had over a thousand registers when expanded.
>Casio has built in functions for some useful equations. For instance I can set a=5,b=6,c=3 and the calculator will tell me that that x=-(3/5)+-(sqrt(6)/5)i.
That's baby stuff, does your Casio figure Laplacians or solve first order differential equations at the touch of a key?
Fourier series and its n-th coefficients? Taylor series? Can you supply binary integers to the command line and SYSEVAL them to call routines at that address in memory directly?
No I didn't think so. The 50G does.
>It represents square roots up to ~9000 algebraically. If I input sqrt(20) it'll say 2*sqrt(5).
Baby stuff.
>Has a 4 line display so you input more info at a time.
50G displays 8 lines of an unlimited-length (bound by memory actually) stack plus a bottom soft menu and a status bar.
>The complex mode automatically multiplies out the i, so if I did i(6i^2+5i-3) it'd simplify it to -5-9i, makes life much easier.

>>54031619
