Just an update.. I bought Casio fx-CG50 last week for less than half the price I got for my HP Prime 3 years ago.. And guess what? The CG50's graphing functions are so much better & advanced.. On 3D graphing, you can set the equations in parametric form.. Plus it can tell you whether a line, a plane, a sphere, whatever will meet or are parallel or skewed to each other which I think is more useful to students than just zooming in or out.. No doubt the Prime is faster but when it comes to "customer experience", the Casio is more fun...

I finally got this to work. My HP Prime was 2015 firmware so it was pretty bad. I updated to 2021 and now Graph3D works but it is still buggy such as when I change the x-min x-max values sometimes it generates an error message for no apparent reason. I have a collection of HP calcs including HP-67; HP41C; HP41CX, HP11C, HP12C. Used to have an HP48G but it crashed.

HP-35, HP-45, HP-67, HP-41C, HP-48GX, HP-Prime 👍😊 All purchased at the time they came out except HP-12C. Still like the HP-67 for 90% of my daily driving…

Yeah the 3D Graph app is the later addition which was not present when the calculator was released and this may explain the limited functionality. However the fact that HP has not improved this app since its first appearance is really disappointing. Maybe since there is a much advanced user developed app they do not care the built in one?

Hmm, plotting a 2d function should be easy enough to do, just add +0y to it, like: f(z)=x^2+0y Not a huge limitation and could even be useful sometimes because it allows to put multiple graph planes slightly apart from each other into the 3d space by adding +0y, +1y, +2y,... if you wanted to.

I tried what you said and it doesn't work on my cx ii cas calculator. f(z)=x^2+0*y will not plot a parabola in 3d.

One thing is to graph the set of solutions of an equation, other thing is to graph a function. y = x^2 is not a function of R^2 => R

Concuerdo mucho contigo, actualmente toda calculdora ha perdido su valor por no salir de casa, las otras tecnologías web y móvil siempre estuvieron ahí, y ahora tomarán el verdadero protagonismo que debieron tener. Espero que la educación evolucione para mejor gracias a esto.

Which is better at graphing: hp prime, hp 50, classpad 2 casio?

Is there any calculator that can 3d graph in any other form without those add in programs?
@Chrls53 жыл бұрын
This tells me everyone is expecting from the calculator to do it all automatically, so that's what all the consumers want??? weird! HP's Philosophy is, "Clients knows what their are doing"

Another graphing function it lacks is plotting a 3-D graph from parametric equations...
