YOOOOOOOO THIS WAS A WHOLE W

[@paragonmathematics7070]

Thanks! Glad you liked it man

[@scramjet4610]

What's this in English?

[@AntonioCavicchioni]

You explain very well. I hope you continue with these videos. Thanks!

[@paragonmathematics7070]

No problem! I do have some ideas for more- life likes to get in the way of videos. Thanks so much for the feedback!

[@darylcheshire1618]

wish I had this in secondary school maths in the early ‘70s. The HP Prime costs around $250, in 1975 the HP65 or HP67 cost about $1000, a good fraction of the cost of a car. My salary was about $5200 a year. Now Copilot can write the progam.

[@GMBDG214]

Hi I just wanna mention that for conversions you can type in your amount, then press the unit button and select your unit, then press sto and then the unit button again to select what you want to convert into.

[@scramjet4610]

That doesn't work in RPN mode; with RPN, you need to push the quantity to convert on the stack followed by the units to convert to in the next stack position down and finally the convert function itself on the lowest stack position, then hit ENTER.

[@Thunder_Light207]

Nicely explained thank you 👍 The G2 Prime is a great calculator 👌

[@johnsanchez1619]

This was great, thank you !

[@eisenhauerca]

Thank you, sir

[@paragonmathematics7070]

No prob bro

[@g.builds]

great video! just switched over from a TI-84 plus CE and was finding the transition a little difficult.

[@studded8054]

How you like it now sense you used it for awhile?

[@paragonmathematics7070]

Great! HP Prime is superior.

[@gabrielceornea9653]

If I wanted to find out an exponential function, for example: 56 grams of yeast grow at a constant rate of Lambda 0,3667 and the question is how much it would grow in 5 days, how would I need to type it?

[@tejara01]

I think it's worth mentioning that you can just hit solve. I don't know if I'm the only one but it seems strange to try parse a value when the equation has an answer. Thanks for a great video.

[@paragonmathematics7070]

I'm not completely sure what you mean, but if you just hit solve, wouldn't you be giving the calculator a "guess" of 0? I put 5 in there because it usually returns the smallest positive solution to an equation. When there's, say, a positive solution at 12 & a negative one at -12, you'd have to specify, because otherwise the calculator won't return either solution.

[@tejara01]

@@paragonmathematics7070 if you look at your example, you're able to solve this without guessing a value for x right? Just using basic algebra will get you there. The calculator has the limitation of only being able displaying one value using the solve app. I get around that by plotting the equation inside the solve app and the graph will logically tell me if there is another solution. Furthermore, the calculator may in some equations, use a random seed making it redundant to enter one yourself. Overall, it doesn't matter if you put a seed in, just hit solve and plot the equation, you'll be fine. I'd like to add that the calculator is a tool and not the solution. So I wouldn't quite expect it to do everything for me otherwise I'd be out of a job! Thanks for your reply Reese. (Hope I spelled that right!)

[@darrenobrien8025]

Thanks a mill

[@paragonmathematics7070]

Of course!

[@TheAmbasador99]

Using this technology is actively more challanging than the math that they are giving me

[@deadstar962]

Nice vid. Maybe I would’ve passed my class if I had this calculator with that nifty conversion feature 😅 but how do you kno how to use these programs? Are there instructions in the Manual for each one ?

[@iguay009]

yea, you have a help button that gives you all the info of the command and also examples of how it works

[@deadstar962]

@@iguay009 yea thanks I found that button it’s really useful and detailed I’m going through the tree one by one. I’ve never had a calculator like this it’s amazing the things it can do.

[@paragonmathematics7070]

Yeah! I wrote most of those programs myself, contained under the "User" Tab when I hit the toolbox. Some programs are written into the computer by the devs, but those User programs I wrote on my own. And yeah the conversion feature rocks :)

[@grey279]

Do you have a download link for the HP prime desktop emulator? I hear that it originally was free for windows but I cant find it from any official HP documentations.

[@paragonmathematics7070]

Sure! This isn't official by any means, but here's the link: www.hp-prime.de/en/category/6-downloads Under the purple tab called "Software" just download HP Prime Virtual Calculator (PC). I'm pretty sure that's why I got mine.

[@powertube5671]

On the second equation I hit "plot" and get the error "Check exactly one equation." How do you get the second plot without the first getting erased?

[@paragonmathematics7070]

So about six minutes in, I enter the equations in. In each line, after you type your first plot, you have to hit Enter. That will put your equation into E1, then move down into E2 and do the same thing. After you have both of the functions into their lines, hit Plot. This should plot the two equations.

[@CaribouDataScience]

How do I update the firmware?

[@technics6215]

Is it possible to store equations somewhere and restore them later? I want to use it for engineering.

[@paragonmathematics7070]

Yeah! The copy-paste tool can hold multiple equations at the same time. I'm not exactly sure how to use it like that, though.

[@aaronyoutube2025]

Hey man, how do you use the explorer app to solve quadratic with a table of values? Since my HP prime does not have quadratic solver in the apps, just the explorer app.

[@paragonmathematics7070]

Not really sure what you mean. You can use the Regression app to find an equation for a table of values- it's really cool!

[@technics6215]

Is it possible to configure it for units like micro, milli, kilo, mega, etc. like in Casio FX?

[@paragonmathematics7070]

Probably, but I'm not exactly sure how to do it. Maybe try going to Settings in your calculator (blueshift-Home button).

[@wing4700]

After I finish working on a equation and start working on another. I still have the first equation in the memories, even after I delete the first equation. How you fix this?

[@paragonmathematics7070]

Not exactly sure what you mean by memories. You mind emailing me a screenshot?

[@michaelbaker5070]

How do you update the firmware on the hp Prime? Thanks

[@paragonmathematics7070]

That's a bit more difficult- you need to download the HP Prime Connectivity Kit, connect your Prime to your computer, and use the Connectivity Kit to update the Prime.

[@nagyelraheb4165]

Can you solve a simple trinomial function like a casio and get your 2 answers?

[@paragonmathematics7070]

Working on it

@@paragonmathematics7070 I found it if you are interested. Press CAS then open the toolbox and pick solve, zeros. Write the equation without the equal zero part then press enter. Thank you for your excellent video

[@dayanajhonson4131]

Is it possible to calculate % ?

[@paragonmathematics7070]

Kind of. Can you give me an example?

[@nagyelraheb4165]

How can you adjust your emulator size? Mine is too big even in compact mode

[@paragonmathematics7070]

Horizontal is a bit smaller than Compact, but I messed around with the maximize and Windows window size change and got it to be small.

[@sarmadalattiya2012]

Why are you giving it a guess of 5?

[@paragonmathematics7070]

Really, you can put whatever number you want in there. The way the calculator works, it finds the closest solution to your guess. I guess 5 because (most of the time) it will give me the smallest positive solution to the equation.

[@doronbarzilay590]

@@paragonmathematics7070 so what if there is more then one solution? the calculator wont show it??

[@paragonmathematics7070]

@@doronbarzilay590 It won't return more than one solution, but the calculator does calculate multiple solutions in the background. For example, if you try to find the solution of sin(x) = 0 and give a guess of 0.1, the calculator will return an answer of x = 0. However, if you give a guess of x = 4, the calculator will return a different answer (x = 3.14). This, and the reason the calculator needs 1 specific guess, is because of the specific numerical algorithm the calculator runs to find the solution. I don't know specifically which algorithm the calculator uses, but on a graph, the calculator will graph both sides of the equation and find the closest intersection to your guess. However, when you hit "Plot" (next to "Num"), the calculator will plot multiple solutions. Hope that infodump helps!

[@technics6215]

@@doronbarzilay590 that sucks! There is no way to get all or 2 solutions? I think TI calculators show multiple solutions.

HP Prime may be a fantastic pocket calculator. I've got it since it came out. But: it is unusable for me, because I cannot read the key captions. They are in a light blue and a light orange, and the are too small. Even with glasses on it is disturbing me. I still like the key caption of e.g. the HP-48S/SX or that of the HP-41 and many of the old ones (which I own all - I'm a long time gatherer of HP calculators). The Prime is a complete disappointment.

[@lambsauce5445]

next time, maybe use windows whiteboard or evernote?

[@paragonmathematics7070]

I'll look into those! I've just been using Screen Snipping for most of these, but Whiteboard/Evernote might make cleaner notes. I'll take a look at both

Thank you for your good presentation but the calculator is surprisingly very basic. I was not impressed at all by its capabilities
