Precalculus/Trig: Verifying Trigonometric Identities
Matching Card Proof Activity!
This matching activity makes for an engaging, scaffolded, low-prep math center! The trig proofs are in order, so the teacher has an answer key already made! All the teacher needs to do is cut out each number and letter card and shuffle them up for the students to sort out!
The two verifying proofs included are:
1) cosx + sinxtanx = secx
2) (cos^2x – sin^2x) / (sin2x) = 2cot^2x – csc^2x
I hope your students enjoy this as much as my precalculus/trig students did! :)
