HPPRIME CAS SOLVING  fabrice48  10192013 I have an HP48 with it i solve some expression, but on HPPRIME,
example :
ON HP48 i do this : then the calculator answer : I=U/R
How to do this on PRIME ????
Re: HPPRIME CAS SOLVING  Helge Gabert  10192013 Try solve(u=r*ii, ii) gives [ii=(1/r)*u]
I used the CAS do to this, and ii (because i is allocated (complex!)).
Re: HPPRIME CAS SOLVING  fabrice48  10192013 it's very strange, i do the same as you but my machine answer this : Re: HPPRIME CAS SOLVING  fabrice48  10192013 i know why :
teh rule seems in CAS only lower cas character allowed.
Re: HPPRIME CAS SOLVING  Helge Gabert  10192013 Yes!
Re: HPPRIME CAS SOLVING  Helge Gabert  10192013 Now I have a question. I'm running the same command again, from the CAS history, and my output is in a different format, in curly brackets and without the equal sign and the variable to solve for. {(1/r)*u} I didn't change any flag settings (that I'm aware of). ????

The upper case single characters are actually builtin variables. Uppercase variables such as MYVAR is fine.

I believe this is normal behavior (the HP Prime does not do everything in the same way as older calculators)
Re: HPPRIME CAS SOLVING  Helge Gabert  10192013 Yes, but when I first ran the command solve(u=r*ii, ii)on the Prime (CAS view) I got this: [ii=(1/r)*u] Now I get this on the exact same machine, with the same command solve(u=r*ii, ii), again in CAS view: {(1/r)*u} Strange.
What output format do you get?
