Topics in Inverse Trigonometric Functions
1
Basic Concepts and Definitions
- Inverse trigonometric functions exist only when we restrict the domains of trigonometric functions to make them one-one
- Each inverse trigonometric function has a specific domain and range called principal value branch
- The graphs of inverse functions are reflections of original functions across the line y = x
2
Properties and Identities
- Complementary angle relationships: sin⁻¹x + cos⁻¹x = π/2
- Reciprocal relationships connect inverse functions of reciprocal trigonometric ratios
- Addition and subtraction formulas help solve complex expressions
