  1. 1Why Inverse Trigonometry Needs BranchesSee how restricting an angle interval makes sine and cosine reversible, and learn to read their principal inverses.
  2. 2The Remaining Principal Branches and ValuesComplete the six principal inverse functions and use their ranges to select exact angles with confidence.
  3. 3Properties and SimplificationUse substitutions and angle identities to simplify inverse-trigonometric expressions while keeping every range condition visible.
  4. 4Chapter Summary and PracticeConnect all six principal inverses, range checks and simplification methods through mixed reasoning and applications.
