Inverse Trigonometric Functions – Form f(f⁻¹(x))

Inverse Trigonometric Functions – Form f(f⁻¹(x)) Function of the form f(f⁻¹(x)): where f(x) is Trigonometric Function (i)Consider function f(x) = sin(sin⁻¹x). Domain of the function is [-1, 1] Also, sin (sin ⁻¹(x)) = x sin(sin⁻¹x) = x for all x ϵ [-1, 1] (ii)Consider function f(x) = cos(cos⁻¹x). Domain of the function is [-1, 1] Read more about Inverse Trigonometric Functions – Form f(f⁻¹(x))[…]
