TI-89 clear variables

  1. Nov 4, 2014 #1
    So the TI-89 can solve ODEs and the arbitrary constants show up as @1, @2, @3, etc.
    Every time I put in a new ODE it uses the next constants @4,@5 etc. How do I clear them to get back to @1,@2 again?

    There used to be a sub forum here on math software etc. but I cannot find it now so I posted it here in the general discussion area.

    That's not it, however I have figured it out. You go to Clean-Up and then chose "New Problem" and hit Enter. Apparently that clears it.
    If someone finds this thread on google then that's how you do it folks!
