1 The Inverse Trigonometric Functions Section 4.2

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

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

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

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

6 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?
