I've changed my earlier question to a more clearer question.
I'm searching for a more easier way to list different formulas in 2 or 3 columns next to each other to create an overview of all the formulas I have to know.
I've used tabular, but that doesn't work with the formulas in mathmode. After that I thought to use the
multicols-environment but then, the formulas were not good aligned. Some are to the top, middle or bottom aligned but not all the same way.
Do someone have a solution to make these lists in 3 or 2 columns easier?
