Rpn is just old, let it die

I have problems with my HP Prime now. please, help me! the buttons are swapped (the "-" decreases the screen brightness and the "+" increases the screen brightness; the "divide" goes to the terminal screen"), and every time I press "Esc", it goes to an "Exam Mode" screen, that has "Configurations - Basic Mode" and to choose the angle. And the Symb button reset. It also does not turn off... I press "shift" and then "off" and it does nothing. And seems like the "On" button is stuck. When I hold down the "On" button, I can change the screen brightness with the "+" and "-" buttons, divide goes to the terminal screen, and Esc goes to exam mode. Please, you can help me? I am from Brazil! Sorry for my english.

Can you solve sin(x)=1 and see if you get the correct answer which is 2kpi+pi/2

If you use simplify() instead of expand(), the Prime gives you the correct answer instantly. I assume expand() is brute force multiplying the polynomials, whereas simplify() recognizes a trick to efficiently compute the coefficients. This is a matter of the calculator doing exactly what you told it too, even if it's slow, since sometimes you need it to do it that way.

Could you show their speed when running a bigger program and see the comparative?

You are a clown 🤡

El teclado de la Hp es pésimo, suena como globos de bolsa

danke für die Information

HP PRIME uses XCAS/GIAC which is far superios, but you wouldnt be able to notice that in this video, but yeah weird bug on the hP.

Amazing Collection

I think you should also compare the 92 to the 92+. I have the manuals for both but only the 92+ unit and the tutorials in the second chapter refer to features that literally are not on the 92+, specifically the Geometry mode where you can draw various shapes. As you know, it's not the same as the drawing tools in the Graph mode.

Wow. 😮

Clown

The 89 got me through electrical engineering no doubt. It was before people realized how powerful it was. The bad part about the 89 is it's keyboard software stuffed in a non-keyboard body.

What is the charger output specifications of HP Prime?

How do you plot greatest integer function?

How can I tell a hp prime G2 other Than the buttons (as they look same as some versions of the G1) im looking for one to buy but not all of them are listed as G2

Cheers for these videos and the intention of sharing what you know about the use of these calculators, however, please consider keeping the whole calculator in the frame of the camera while filming. Sometimes it's hard to follow what you are doing if it is not possible to see what keys you are pressing and, consequently, the result in the calculator screen.

You have bought too many HP Prime. I know the latest is the Hardware Version D that the model number is 2AP18AA. The SHIFT button is deep blue colour! EVEN the summation is the fastest among the advanced sci-calculators by its advanced processor!

What firmware version does the 48gii have?

I think I need a guide book or attend the related lessons to learn how to run this series advanced graphing sci-calculators of TI... I use CASIO so I do not know TI🤣🤣😅😅

Use simplify!!!

lol, mine does it in CAS mode using simplify instantly. Not even 1ms. This is not accurate!

I know HP Prime is the fastest advanced sci-graphing calculator but might have little bugs that we do not know now. The problems can be solved by renewing the software. The importance is the import, export to the PC or universial interface.

Mano pero con respecto al multitáctil de las aplicaciones de calculadora pienso que ni siquiera las calculadoras físicas tienen esa opción y no es como que uses de eso en un caso de la vida real. Lo que se premia de estas calculadoras es el multiuso que pueden brindarnos a un costo relativamente bajo respecto a la compra del equipo original. Lo que sí te doy la razón es que este tipo de aplicaciones deberían de darle un mantenimiento y brindarnos un diseño completamente responsivo porque por la cantidad que están pidiendo creo que no es mucho pedir desde la comunidad. Como te digo por 20 dólares no encuentras una calculadora de segunda mano que pueda asemejarse a esto y ayuda bastante más porque prácticamente hay versiones gratuitas y si es un gran apoyo tener tales herramientas a disposición.

I've only used Free42 (an open source HP 42S implementation) for a few days so I don't have a lot of experience on RPN, but I do know how to do integration, solve equation, etc. I've used HP Prime for a few days and I must say its RPN mode is pretty usable. It has an infinite-level stack so you can always input numbers from the left to the right without worrying your inputs getting pushed off the stack (things like 1-2/3^(4+5), and I know the more proper RPN way is going from the inside to the outside, but it requires a bit more extra brain power when you need to flip operands). If you run a calculation by mistake, you can recall all operands by pressing Shift + '+' (ANS). The "Last X" however, can only recall the last operand, so you need to do a reverse operation first if you need to recall the first operand. It has a big touch screen and you can highlight any stack level and do things like roll up/down, drop, duplicate upon only a portion of the stack. You can run any functions by pushing arguments into the stack first and calling the function with/without the number of arguments to consume. You can integrate textbook notations (including CAS) seamlessly by using single quotes and Shift + ',' (EVAL).

48sx is the pinnacle ... also readily available as Droid48

Have the titanium and hp41c,48,50 and dm41x. Mainly a hp fan as that would suggest lol

Does the HP Prime offer a CAS variant and an Exact Math Engine variant?

Worst demonstration video I’ve ever wasted my time to watch. This guy hasn’t a clue what he’s talking about.

Please let me purchase one of these from you. Hp Prime is not available in India.

I think my HP39gs cannot expand that long terms... if I won't mind the bugs of the HP Prime and can avoid it, this would be a good tools in the work fields...

If you are strong in Maths and fast learning, cheap sci-calculators are still good use in different fields for the practical cases.

How can I classify the latest version of HP Prime???

Time is gold, I won't care of the money to purchase the best one!

7:45 This is not true. You can display several outputs on the same line, including results etc...I meant to say to that it's not possible at this stage yet, since we hadn't covered string concatenation

Hi mate! I wanted to know how i could install the update.

Your vid’s are my goto for TI-92 info. Outstanding info!

Hi, very interesting. For x=1 to 5896 it works, but from 5897 to 5938 you obtain "iquo Error: Bad argument Type" and from 5939 to 10'000 you have "undef"

How do we change the date and time😊

This video is very helpful.

Obviously, any suspected lack of capability or competency does not reside on the product side.

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.

HP Prime has the most intutive graphing due to touch screen also you can have tick labels too

How do you find these deals? Ebay or something?
