You're certainly allowed to talk about the problems with your classmates and ask me questions if you get stuck, though copying your classmates' solutions is not allowed and will be considered to be a violation of the UConn academic integrity policy. I will ask you to write down the names of any classmates you work with on your homework assignments. You are allowed to use any kind of calculator you like when you do the homework, but I urge you not to rely on it heavily since it will not be permitted on exams (rather like your classmates' help!).
Each term, I ask my Math 2710 class what strategies they'd found useful for the homeworks partway through. I've compiled the ones that I was given permission to share. Your class's can be found here; the tips that my Spring 2012 class came up with are here.
