Trying to figure out these formulas

I know this is kind of an odd question, but I'm trying to work on a test project and have some formulas I found that I want to try, however, I'm not sure exactly what these are.

If anyone recognizes and can point me in the direction for more research/info on their use I would
appreciate it.


I'm not sure I understand your question.
