Thanks for taking the time. I have all kinds of projects in mind,& am teaching myself coding etc., so I'll need a good calculator sooner than later. I'm going to be on the lookout for one second-hand, or even hand-me-down just to start out.
I enjoyed this video on calculators! Definite thumbs up! I also tend to be a calculator nerd. :) Your two high-end calculators often can't be used on standard tests, including the F.E. (that was called E.I.T when i was in college) because they can solve some equations/formulas/functions that would make passing the tests too easy without really knowing how to solve the problems yourself. However, the Casio fx-CG50 can be set into a "test mode" which is accepted in F.E. tests. I assume that you must set it in the test mode before entering the test location and show it to the Proctors -- it will have a color bar flashing on the screen that proves that it is in test mode. Other TH-cam channels have Playlists of tutorials on both of your higher-end calculators. A (too) quick showed Playlists of ~8-9 tutorial videos on the TI Nspire and >40 tutorial videos on the Casio fx-CG50. Surely there is a longer Playlist for the TI too. (I found a tutorial for my TI-89 Titanium that was nearly 100 videos!) TI's CAS (Computer Algebra System) is (or was originally(?)) intended to show that you don't have to learn RPN as used in the HP calculators back when they were the two top calculator manufacturers. I _think_.... I saw a video or web page a few years ago that explained why the TI calculators tend to cost more than many other calculators. TI has embedded into "education" at virtually all levels for many years and are often required in those classes/schools --> cost more because of relative lack of competition. (This paragraph is from a foggy memory, so I may have it at least partially wrong.) In the past, I only used TI calculators because they cost less than the HP calculators and were easier to understand without having to learn & get comfortable with HP's RPN. My first 3 TI calculators all cost the same: ~$120! In mid-'70s dollars, '80s dollars, & about 10 years ago when I bought a TI-89 Titanium. I also have one or two Casio calculators, like the fx-991 (whatever version) and an old Radio Shack Programmer's calculator that runs on one or two AA cells and the batteries last 10+ years, even with it's clock function running 100% of the time. Of course, it's not a scientific calculator, so I don't really count it. I'd like to get an HP or an HP-clone calculator just to play with and learn the use of an RPN calculator.
