Does anyone have suggestions for a quick reference guide that was useful to them for brushing up on basic math (algebra, trig) for Gen Chem and Physics? I'm looking at the ___ For Dummies books and a few others. Thanks!
go on amazon and buy a used text book that is a non current edition. they cost like 2 dollars. lots of problems, explanations....and cheap 🙂 Cap't Thrifty Approved!
