    Ti-89
In summary, the speaker found out that their TI-89 calculator had a booklet explaining how to use it, and they were able to successfully use the integrate function to solve a problem. They also mentioned exploring other features, such as summations, for their pre-calculus class. They expressed gratitude for the helpful information.

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!
