Impose variable greater than zero - TI-Nspire CAS


Is it possible to impose x>0 in the scratchpad of TI-Nspire CAS? The Define allows only to define a variable x=something.

Thank you for your help.


Solution

  • You cant do it while defining the variable, but you can use “|” operator to constrain the results of expressions:

    fMax(0.5*x^3-x-2,x)|x≤1
    

    x=-0.816497

    solve(tan(x)=1/x,x)|x>0 and x<1
    

    x=0.86033358901938
