Hi, I'm making an equation sheet and I am having some minor problems with it. For some reason I am getting an extra page of output before the actual equation sheet. I don't know what is causing the problem, but I have never used the minipage environment before so it may be my inexperience with that. I am attaching the .tex file (named .txt because I cannot upload .tex files to this server) and the .pdf.
I really would appreciate someone taking a look at this and letting me know what simple mistake I'm making.
