Need an experts advice: which is currently best CAS? - Mike (Stgt) - 04-11-2012

My son was impressed when he saw me using CAS on an HP40G. At school he must use an TI84+. Now I want buy him a CAS "toy" to play at home. What is the experterts advice: TI Nspire, HP40GS or an HP50G? Or even a PC program?

Ciao.....Mike

You can try Bernard Parisse's XCAS on the PC which is free. As a calculator, the Voyage 200 or a used TI-92Plus (better keyboard but bulkier and less flash memory) is powerful and user friendly. Coming from a TI-84, your son should feel at home with relative ease. The TI-89 has the same software but a non alpha keyboard which makes it less comfortable to use for CAS.

A 50G has the same problems as the TI-89 (keyboard), is certainly more powerful but less easy to comprehend.

As a middle school math teacher, I would recommend the TI-NSpire color CAS. Many schools that are using the 84+ now will probably be eventually upgrading to the NSpire. If he ever gets into programming, he can choose between TI Basic or Lua on the NSpire.

I second Don Shepherd's choice. The TI NSpire CX CAS is king!

What about Lua? - Namir - 04-11-2012

Don,

Can you shed more light on programming with Lua on the TI NSpire CX CAS? I am very curious about it. I have also seen Lua for the iPad and iPhone.

I would recommend an HP40GS. You and your son can explore this calculator together. I'm sure he will enjoy the common "game".

After that your son should decide himself wether he will use an HP or an TI in future.

Bear the HP39gII in mind. Perhaps sometimes this calculator will released with CAS.

Hi all,

I've just gotta ask. Although personally I put HP calcs at the top of my list, wouldn't HP Graphing Calculators, especially the 48GX and 50G surpass TI's in many ways?


Re: What about Lua? - Don Shepherd - 04-11-2012

Namir, see this link for NSpire Lua documentation and tutorials.

Not having a color NSpire, I haven't tried it myself, but I have seen some screenshots on the google NSpire forum where some folks have indeed created some Lua scripts that run on the NSpire.




Much thanks to all experts - Mike (Stgt) - 04-11-2012

Thank you for your kind help. Suppose I will get a HP40GS for me and a Nspire PC software teacher edition for my son. :)


Re: Need an experts advice: which is currently best CAS? - bluesun08 - 04-11-2012

You are right, but the 48GX has no reasonable CAS and the 50G is IMHO for a beginner to complicated and has no reasonable manual.

I think the HP40GS is a nice beginner calculator for his son to play with.


Re: Much thanks to all experts - bluesun08 - 04-11-2012

If you have a CAS-PC software in mind i would recommend Mathematica, Maple or GeoGebra (CAS) immediately.


Re: Need an experts advice: which is currently best CAS? - hpnut - 04-11-2012

I say go for the hp 50g. Look at this for good instructions to use the 50g.

"These notes show how to use the hp 50g, (or hp 48gii, hp 49g, hp 49g+) and ti 89 titanium (or ti 89) calculators to solve problems in dynamics."


Re: What about Lua? - Namir - 04-11-2012

Thanks Don for the link to a wonderful site about the TI NSpire and Lua!

Re: Need an experts advice: which is currently best CAS? - Matt Agajanian - 04-11-2012

You're right! Excellent resource for the 50G. I just downloaded the modules. That way, I'll go through them slowly and methodically.

I recommend introducing him to Geogebra (free software for PC, available for most operating systems). The user interface is very well done, and it makes geometry come to life. Truly a wonderful math toy (although not a CAS in the traditional sense of the term).

Hi,

I recently switched to maxima (with wxmaxima frontend) at work. For my purpose it's a true mathematica replacement (very similar syntax), and it's free.

Once more: thank you! - Mike (Stgt) - 04-16-2012

Today I saw the latest appends. Gives me some more chances to make math "sexy" enough for my son. <VBG>

On this site of Colin Croft he references a manual from Renée de Graeve with an interesting aspect:

Democratisation or just undermine math teachers' authority?
