HP Prime Summation Problem

Hello,

 

I have a problem with the HP Prime and I have been trying all day to resolve it, but I couldn't.

 

I just want to do a sum and I always get an error. I join a picture of the error message.

 

Could someone tell me what I am doint wrong?

 

Thanks

Re: HP Prime Summation Problem

Hello,

 

The root cause of the problem is that the CAS does not support comma as a decimal separator. Selecting comma causes the sigma template to generate ; as arguement separators which is also not supported by the CAS.

 

I beleive (not sure) that the latest public release of Prime did fix this issue (by having the template recognize that you are in CAS and generate ',' as arguement separators). Which version do you have (click on help, tree, HP Prime to see the version number).

 

Other woraround with the older (august) version includes:

- using '.' mode instead of coma mode.

- Switch to Algebraic (instead of textbook) input

Re: HP Prime Summation Problem

Hello Cyrille,

 

Thank you for your answer.

 

I'm on software version 2013 8 13 (5106) and CAS version 1.1.0

 

How can I solve my problem?

 

Regards

Re: HP Prime Summation Problem

I entered your summation problem, as shown in your photo and it works fine (answer= (Pi^2)/6).  My Prime's version is as of 2014 11 25.

 

I would suggest updating your firmware.  That can be done through the connectivity kit for the Prime.

Re: HP Prime Summation Problem

I should have type 2013 instead of 2014 (I don't get future updates!), so 2013 11 25

That's too bad. I would have liked to see what we'd be up to for the next year! :-)
