Anyone know how to do the animation you see in the presentation video of the HP Prime at 45 seconds start? It is cool

this is the link of the Video

That's done in the geometry app. Check out the slider function, cmds/plot/slider. I made some cool apps to teach my kids dilations, transformations, etc. I thought they were cool but they were not very impressed. Kids ... go figure.

Excellent Carlos295pz, I'm going to try it anyway, and I suppose as well as you did drop the stroke drawn from the external point to the circle that I think corresponds as a graph of the sine or cosine function !!! !!! Thank you ...


Note: I thought the point E in the circle could be with the PointOn command but I do not know if it will work either.

Hello,

just for info, the Instruction geometry function will return a string the details all the instructions in the app. This makes giving geometry instructions sequences easier...

Thanks for the tip Cyrille

Hello!!! Carlos could you specify a little more the first parameter Angle, how did you define it? Is it defined on a point in the circumference with the pointon command or is it otherwise? In addition how is it done so that the plot of the animation is on the screen and not deleted in each animation? Thank you

Slider and trace

In other calculators as TI-nspirecxCAS, classpad400 or numworks we can do this, with the native commands?

Hello,

Stupendous! Very nice work! I loke the solar system and cylist!

Hola y muchas gracias "el amigo Carlos".

Lástima que no entiendo bien el español, veo todos sus videos en sus sitios web. Gracias otra vez !

Great animations, I like them! Also a nice tutorial, even if I don't understand a word you are saying.

Yeah, I'm waiting for my Google Babelfish earbud. Hopefully the wait won't be as long as for my personal jetpack!

Hi,

I've an issue with Carlos'solar system.
I only have the half planets ?!

Surely a configuration problem but I don't see where.

Do not worry, it's not a bad configuration, it's a problem with the current firmware dragged from the last betas. The video had to be done with a previous firmware. Even in my language the user manual shows it. It's just a problem with filled circles.

At least they are half full!

Hi,

Thank for the quick answer. Fortunately it is only planets and not glass of red wine ! I'm french (old) man and I prefer full glass of red good wine than a half one !

Hahahaha !
