Calculators Inequalities with TI-89

  1. Sep 28, 2005 #1
    I've got a TI-89, with which I'm trying to solve an inequality. Not a specific one, just in general. I try to use the 'solve' command just as for equations but with an inequal-sign instead, but it doesn't work. Anyone?

    But places where the sides are equal separate places where they are "<" from places where they are ">". If you don't have too many solutions to the equation, check one point between two solutions to see if that region gives ">" or "<".
