Ok I'll ask my question a different way.
we are trying to decide between TT's Pre Cal and Saxon
Advanced Math.
What is the difference between trigonometry and pre-calculus? (can you tell I never made it that far in math?)
DS has taken through ALG2 and Geometry in Teaching Textbooks, but I don't want to throw him into TT Pre-Cal if there are skills he could benefit from in the Saxon Advanced Math.
thanks for any help/input.
