The attempt at a solution My problem is that I don't even know where to start on this! My first problem is always forgetting what I can and can't use, cuz we can only use pretty basic stuff, only the stuff we have already proven. (For anyone not familiar with the Spivak book.) I'm so confused on where to start, so if anyone could help me plot out some sort of plan for a couple of these, I would be so grateful! I'm really struggling with this course because I don't know where to begin. After we do these problems in class, I understand them, but trying to do the homework before is my problem. I don't mean to look like I haven't attempted this and am looking for an easy way out -- I've been thinking about this for quite awhile now and I'm still stuck.
