Calculators How do I calculate this on a TI-89?

    [tex] f(x) = 2x^3 [1,3] [/tex]

    [tex] \int_1^3 2xdx [/tex]

    My TI-89 came with a booklet, such things were described there.

    I would be not surprised if the same booklet is available from the TI site.

    But I don't feel like checking now, so I just tried integrate(2x^3,x,1,3) - and it worked.

    It works, I never knew you could do that. I went on to summations, etc., as I am in Pre-Calculus and we go through all the steps, definition of integral and the such...

    Thanks!
