Trigonometric Proofs

Activity Overview

Students will perform trigonometric proofs and use the graphing capabilities of the TI-Nspire for verification.

Key Steps

  • Image

    The first step in each problem is for students to prove the equation algebraically.

    After proving an identity, students will graph it for verification. Emphasize with students that the graph only verifies what they have proven by hand—it in no way constitutes a proof.
