Lesson Plan

Illustrative Mathematics: F Tf, G Co, Trigonometric Identities and Rigid Motions

Curated by ACT

The purpose of this task is to apply translations and reflections to the graphs of the functions f(x)=cos x and g(x)=sin x in order to derive some trigonometric identities. There are also rotations 180 degrees about points on the x-axis which preserve these graphs but these have the same impact as the reflections. Aligns with G-CO.A.5 and F-TF.A.2.
