Today I was giving back the assignments to the lecturer and sending my TeX so solutions could be completed...
Lecturer: What is this "pmatrix"?
Me: Oh that is in amsmath, it does a matrix with round brackets.
Lecturer: WHAT??!!! I have been doing that manually like a child!
Should I point out the wikibook with all my cheats?
@vam103 Have a look at the physics package. It contains a ton of useful macros/shorthands building on top of amsmath. I use it when I'm taking notes during lectures.
@j Mostly I use the mathtools package now rather than amsmath. Also probsoln is really good for the assignment sheets.
Have to check out that physics one.
Also everything starts with nag so I stay sort of current.
