If you try solve(q=((0.8492*pi*d^2)/4)*(d/4)^0.54*(h/t), t) Ti Nspire don´t work. HP prime is better in this case. If you look at the history of Derive, you'll see that Texas hasn't improved CAS at all. He only bought Softwarehouse, but it seems like Texas doesn't know anything about CAS.
I watched because I’m considering getting one. This was not a useful review. 4 minutes of you getting frustrated because you clearly haven’t read the manual does not help my buying decisions. Didn’t watch the whole thing.
The eRPN on the Prime is fine and you can enter equations in RPN mode as well, you just do it differently to how you do it on the 49. Maybe read the manual ;-)
Great video! There are things you didn't mention. I am searching calculator which can calculate vectors and also which can do curl, divergence and laplacian - these are vector calculus. HP 49G has these functions, I am not sure if TI89 titanium can do these. In terms of practicality and speed TI is better.
A more didactic approach would be to go to the respective solve menu, solve a couple of quadratic equations (real solutions, complex ones) and afterwards try out the options and individual flags that influence the solving. I think starting with the flags distracts unnecessarily from the purpose of the video.
Hello! Thanks for the video! I wanted to ask a question: why is it that after the update when I type in anything which is supposed to give answers in terms of pi or a fraction it just returns a decimal, without me being able to view it as a rational form or in terms of pi. for example, Arctan(1/√3) returns a decimal which I can't make In terms of pi when clicking a b/c. Any way you could check and let me know if you encounter the same issue? also, this happens in the normal home mode, in CAS mode it works, but I need to do it in normal mode as CAS mode is disabled during examinations. Thanks!
@@calculator_boy Oh wow, ok so it's not a one off thing. Do you have any 92 or 92 plus units that you'd be willing to sell that have lines in the display? Horizontal, vertical, or both.
The RPN works perfectly, I'm not sure why this guy is having such a hard time. I'm hooked and wish RPN was available on more calculators. There are more statistics functions than the TI84, more functions in general, really. Matrices can handle complex numbers natively, which is really nice. Complex math in general is really nice, you can switch between polar and rectangular form in two keystrokes. You can put complex numbers into functions like cosh and sinh. The touch screen makes the ridiculous number of functions available easier to find and use. The notes can use special characters like alpha and beta (or a thousand others), and you can make notes in textbook format, which is why you should NEVER use that amazing functionality to cheat on tests. You can change bases like octal, hex, and binary. I had a TI84 Plus right when they came out, and that's what I started college with. I wish I got the Prime right away. It would have helped a lot to double check my answers using CAS since I waited until I forgot math to go back to school. Plus, I wouldn't have had to use SIMULINK for complex matrices. That was never fun.
I have the same problem as you. Lol. I love programmable computers, that pretend to be calculors. Lol. I collect calculors too. I have a Ti89, Ti titanium, Ti inspire 2, HP 33S, HP48SX, Hp50g, HP prime g2, and also a few others. I am fascinated by them. I am a ex Nuclear engineer in the Navy. I once wrote a simulator of my Nuclear Reactor using an HP48SX, using equations that they gave us, all the other engineers were impressed because it was accurate. Lol My favorite calculator by far is the HP50g. True Rpn, probably the best HP calculator. The prime is super fast though... I use Emu48 on my S21 Ultra. I set it up to emulate an Hp50g, it's super fast that way. I love Emu48. My phone does 108 mflops. Lol It's super fast, I got the 189 page user manual for the HP 50g, off of ebay. Still want to get a Voyage 200 though.
Love to hear it! I'm still wanting the 50g but not willing to spend close $200 on it lol. Emu48 is by far the best emulator for hp enthusiasts. For TI enthusiasts, 'Graph 89' is the way to go. It's about $4 and has the 89, 92 Plus, Voyage 200 and a lot more. I made a video about it. Also, all my programming videos were made using Graph 89.
How are you not scaring everybody at Planet Fitness? Part of your training has to have so much control. Which is a great aspect a lot of people do not utilize.
It's interesting to see how far this had evolved from the early personal computer BASICs with line numbers. The Sharp pocket computer I had was more like those. BASIC perhaps wasn't the most appropriate programming language for a calculator, but in the 1980s it had the huge advantage that many people already knew it, so the learning curve was gentle.
For university (general engineering) which would be the better choice HP prime g2 or the Nspire CX II Cas? Regardless of what is allowed in exams. currently i have the Casio fx-991EX which was fine for my high school.
I am having trouble with this process. Anytime I plug in my 92 plus, I can't get the TI connect software to connect to it. When I open the TI device explorer, it just endlessly says "trying to connect". The program stops responding. I know the cable and calculator work fine since it tells me a 92-plus is attached. I am using windows 10. Any tips?
