I have A LOT of problems in work sheets to do before my midterm on friday for calculus. The thing is, I don't have the solutions but I do have a TI-89 and it helped with checking my answers for integrals. My question is, how do I (or even can I?) work with infinite/power (see if they converge, diverge, etc..) series with a TI-89? I only have the manual as a .pdf file and I can't find anything in it but I just want to make sure that I'm not missing something... Thanks for any help.
