Calculators Having problem with using ti-89 titanium solving integral problem

  1. Nov 21, 2008 #1
    I just bought my ti-89 Ti
    Please help me with this problem.
    I can't get the right integral, instead I get a matrix look output.
    Check the picture I attach to this post, then tell me what I should do to have the right answer.

    Thank You

    My guess is that you have 'x' defined as a matrix right now. You need to clear 'x', or use a different variable.

    Thank You, I don't know how to clear 'x', but I just reset my calculate, so everything works fine now.
