MAFS.912.F-TF.3.8

Prove the Pythagorean identity sin²(θ) + cos²(θ) = 1 and use it to calculate trigonometric ratios.
General Information
Subject Area: Mathematics
Domain-Subdomain: Functions: Trigonometric Functions
Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Prove and apply trigonometric identities. (Algebra 2 - Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
