HP Prime screenshots - Mic - 05-16-2013

Hello, here are screenshots of the new HP Prime.
The calculator can draw anything you want : any relation between x and y. For example, sin(x)>sin(y) or x Mod y = 3 etc...

The graphing commands are particularly impressing :

You may call me conservative but that's a bunch of nice examples where color doesn't add any value - b/w graphics would have sufficed.

Just one counterexample:

There's an unmatched left parenthesis in this formula:

It appears HP was never good in handling parenthesis.

BTW: Is this a Moiré pattern in that graph?

WOW, that's really looking impressing!

Seems to be the most powerful calculator currently - except my TI-92+ of course. ;-)

Can't await to get the emulator ...

You can do that with a slashed line instead, for example.

Re: HP Prime screenshots - Tim Wessman - 05-16-2013

Yup, when you get right down to it no color could be just fine. It is just kind of expected at this point though. There are some good things that can come out of it. High power draw is definitely not one of them.

However, I guess when you get right down to it, anything beyond fingers and toes is not needed for math... :-P

Re: HP Prime screenshots - bhtooefr - 05-16-2013

You could, but color makes it easier to see.

My main concern (and I see the 39gII does it too (but not as badly, there's only a couple pixels between an exponent and its base)) is how high the exponents are above the base. Will that formatting be tweaked to lower the exponent by a few pixels, so it doesn't look like a new line?

Ouch. Enter key placement !!


Re: HP Prime screenshots - Gerson W. Barbosa - 05-16-2013

Why bother? Let's get back to that :-)

That must be a "ouch" of pleasure at the first HP calculator in 30 years that has ENTER placed appropriately...above those /x-+ keys with which the use of ENTER is most intimately linked. It was gross incompetency in ergonomics that allowed the ENTER to remain on the left after the /x-+ keys were moved right.


Re: HP Prime screenshots - Ángel Martin - 05-16-2013

Now you're talking !!! ;-)


Re: HP Prime screenshots - Mike Morrow - 05-16-2013

Here's the direct link to HP's May Presentation on the Prime.

This original user (but not purchaser...way too expensive) of the original HP-35 is impressed by this latest generation.

For sure we've never seen a Truth plot before.

Somehow I had difficulties to match your plot with the purple plot of the brochure until I noticed the difference:

Kind regards

Re: HP Prime screenshots - Gilles Carpentier - 05-16-2013

Where is this brochure you refer to ?

The 50G do it, but it's very very slow...

Re: HP Prime screenshots - Gilles Carpentier - 05-16-2013

With my 50G, i've not this problem

I've a parenthesis 1/Sqrt(2*PI) ....

Same on my 48GX. Only the leaflet is wrong.

WolframAlpha is running in a timeout. That plot could become our new benchmark. I wonder how long it took the HP Prime to draw it.

Cheers

Re: HP Prime screenshots - Gilles Carpentier - 05-16-2013

Thanks Thomas,

It seems the right equation to get the plot of the Prime is more something like :

but not exactly ;)

The equation in the brochure is not the good one ...

Re: HP Prime screenshots - svisvanatha - 05-16-2013

No, it was an "Ouch" of pain. While I can appreciate the ergonomic advantage of having the ENTER key above the -+*/ keys, I started my HP life at the time the 42s came on the market. I find it unnatural to have the ENTER key anywhere but on the left, and the arithmetic operators on the right.

I believe that was forced by the radical keyboard re-organization that was necessary by the unfortunate choice of landscape layout for the Voyagers.

When the post-Voyager HP machines returned to the more natural portrait configuration, the ENTER and /x-+ keys should have been re-united. It doesn't really matter which side, as long as all five keys are on the same side. Personally, I find as a right-handed user that the right side of the keyboard is the best for these keys. I have no idea why HP in 1971 decided these five keys should ever have been on the left side, given that only about 20 percent of the world population is left-handed. Perhaps it was an evil left-handed (forgive the tautology) HP manager's conspiracy. :-)

I started with limited use of somebody else's HP-35 as an EE undergrad in 1972, and got my own HP-67 in 1977. I've experienced all variations from the time they were introduced. All except the unique new HP Prime layout. The Prime will soon be available, and its ENTER and /x-+ layout is perfection for the very first time in HP history, at least for right-handed people!

Hi, Mike.

I am right-handed but prefer to have on the right side the digits, I don't understand why so many people prefer operators there... :)

Strange thing is that I am equally used to the numeric keypad on my computer keyboards, with operators scattered on top and right sides and enter on bottom right. Funny how our brains work.
