With logb(x,b) Works, thank you very muchparisse a écrit :The log template of the nspire is not recognized, try log_2(3.0) then enter. Use natural logarithm or logb(x,b) instead.

Re: solve logarithmic inequalities with hp prime and khicas
Both with prime and Khicas i use the template "log" of the two calculators, then I enter 2 as base of the logarithm.parisse a écrit :Can you enter the precise commandline (algebraic syntax)?
There is no log2 function in giac.

solve logarithmic inequalities with hp prime and khicas
Goodmorning everyone,
Parisse, do you know why when I solve log2(3+x)+log2(3-x)>=1 hp prime otput x>=-sqrt(7) and x<=sqrt(7) and with Khicas output x>=-sqrt(-e^1+36)\2 and x<=sqrt(-e^1+36)\2?

Re: use of Khicas and Xcas
The problem is with gdb whatever the interface. I'm debugging myself with emacs and gdb or even with gdb in console mode, and that failed (segfault or breakpoint not working, I don't remember). But this is a gdb problem or Khicas problem? Because if the problem is gdb you could change Program for d...

Re: use of Khicas and Xcas
Have you tried with:
Eclipse CDT
Qt creator
Visual studio
Code blocks
Kdevelop
Are good debugging environment for programs in c++.
They don't work with Khicas?

On ti-Planet Adriweb, which is a very good programmer on ti-nspire, says that this is the better
Method to debug Khicas, but I think It's the same you are using.

Re: use of Khicas and Xcas
There are many areas where Xcas contributors would be welcomed. Some of them: * for khicas: what is missing is a good debugging environement.

Re: use of Khicas and Xcas
I recommend the HP unless you need multi-precision floats : with the latest beta firmware most of the Xcas commands are available and there I have the tools to fix bugs, assume works for example. In any case, is it possibile for us users to help you improve Xcas? Since I use Khicas a lot I was wond...

Re: use of Khicas and Xcas
However, can I ask you what is the better and most powerful between
Khicas and the cas installed on the Hp prime?
Obviously for the calculation part

Infact now it works on my app, on Khicas output an error with the argument (bad argument).parisse a écrit :That's normal, you must enter the 2 commands in 2 separate commandlines or add a semicolumn (;) between them.
It says me to solve assume(x>-pi && x<pi), despite having already put in the input.

Re: use of Khicas and Xcas
Inside Xcas, the syntax is: assume(x>-pi && x<pi) solve(sin(x)>1/3,x) Unfortunately I tried with khicas, it does not work with khicas, I don't know why... Thank you very much, i also tried now with Khicas and this syntax but output: Undef((sin(x))>1\3,x) Also on the app of Xcas that i have on my Ph...
