Key Topics to Revise

1

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
2

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
3

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
4

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
