the weekend i have a calc test.. the teacher says that we must know if the problem needs intergration by parts without him stating that. i m really not sure how i would know this.. for the most part the book we use divides the homework into sections using substition, intergration by parts, long division, etc..
so i guess my question is.. how do i know when i have to use intergration by part?
also any general advice on mastering intergration (anything u find helpful) will be helpful for me. thanks.
