Revision Notes — Inverse Trigonometric Functions
Key concepts, formulas, and definitions from Inverse Trigonometric Functions for JEE Advanced Mathematics preparation.
Key Topics to Revise
Concept and Definition of Inverse Functions
- A function f⁻¹ exists only if f is bijective (both one-one and onto)
- Trigonometric functions are periodic, so we restrict their domains to make them bijective
- Domain of f becomes range of f⁻¹ and vice versa
Domain and Range of Inverse Trigonometric Functions
- Each inverse trigonometric function has specific domain and range restrictions
- These restrictions ensure the functions are well-defined and single-valued
- The range of inverse function equals the restricted domain of original function
Graphs of Inverse Trigonometric Functions
- Graphs of inverse functions are reflections of original functions about y = x
- Each inverse function has characteristic shape and behavior
- Understanding graphs helps in solving equations and inequalities
Principal Values and Function Composition
- f(f⁻¹(x)) = x for x in domain of f⁻¹
- f⁻¹(f(x)) = x only when x is in restricted domain of f
- Composition properties are essential for simplification
