I've been using OpenOffice and/or MS Word to do my college assignments, but since I started this new discrete math course, I'm finding myself very annoyed with the math formula options in those programs. I learned about LaTeX and figured it would be my best option. Since I really just want to get my college assignments done with it and not use it for printing books I've written or anything, I decided to go with LyX. It has a quick and easy preview option, and isn't so different from what I'm used to. I still can't find a way to make the fancy, cursive script "U" that represents universe or universe of discourse that is used in set theory. Is there a specific package I need, or did I just miss it somehow. Also, if I do need a new package, how is that even done with LyX. Anyone with assistance has my gratitude.
