 # Trigonometry (A Challenge Option)

## Goal

Trigonometry in Math 4 / Calculus is a challenge option (required for Honors students) that reviews the basics of trigonometry and then introduces trigonometry that will be seen in college classes. The trigonometry that is reviewed/learned here is incorporated into the main class through challenge options on handouts, assignments and homework. ## Handouts
