The Inverse Trigonometric Functions Section 4.2

Objectives Find the exact value of expressions involving the inverse sine, cosine, and tangent functions. Know the definition of the inverse secant, cosecant, and cotangent functions. Use a calculator to evaluate sec -1 x, csc - 1 x, and cot -1 x

Find the exact value of sin - 1 (sin 5π/4)

Find the exact value of sin(tan - 1 (1/2))

Find the exact value of cos(sin -1 (-1/3))

Inverse Functions csc -1 x (Domain [-π/2, π/2]) sec -1 x (Domain [0, π]) cot -1 x (Domain [-π/2, π/2]) Meaning: The cosecant/secant/cotangent of what angle equals x?
