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 in Desmos, assignments and homework.
