    • eval command

    Extra for experts 

    Think how you can limit that the frequency is not too low or too high?

  • Solutions

    TI-Basic Code

    Define sound()=
    Prgm 
    Request "Frequency",f 
    Send "SET SOUND eval(f) TIME 2" 
    EndPrgm

    Notice: You can't copy-paste it because it includes HTML formattings

    TI-Basic Code with min&max

    Define sound()=
    Prgm 
    Request "Frequency",f 
    Send "SET SOUND eval(min({max({f,50}),1000})) TIME 2" 
    EndPrgm
