Calculators Help with TI-89 Calculator

  1. Feb 2, 2009 #1
    My problem is that I don't understand how to really work my TI-89. Today I wanted to make more space so it wouldn't work so slowly, but I deleted majority of my applications without meaning to. I don't know how to get these applications back either, please help!!

    You are screwed man. Once you delete something on TI89 it is game over. I hade the same and by deleting files you will not speed it up , anyhow that is over now. sorry.
