   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!
