Useful

Its a very good listing of useful formulas in high school/college math. I noticed two small errors (the abs(a)>=0, not just >0 and the change-of-base formula actually needs to CHANGE the base) and the formatting had a weird moment (why are the if...then statements for lHospital with two bullet points while all other conditions are in the same one?).
