834 Foundations of <strong>Trigonometry</strong> (c) Since the argument −2 is negative, we cannot directly apply Theorem 10.27 to help us find arccot(−2). Let t = arccot(−2). Then t is a real number such that 0
10.6 The Inverse Trigonometric Functions 835 y 1 θ = arccot(−2) radians β 1 x π (d) If the range of arccosecant is taken to be [ − π 2 , 0) ∪ ( 0, π ] 2 ,wecanuseTheorem10.28 to get arccsc ( − 3 ( 2) = arcsin − 2 3) ≈−0.7297. If, on the other hand, the range of arccosecant is taken to be ( 0, π ] ( ] 2 ∪ π, 3π 2 , then we proceed as in the previous problem by letting t = arccsc ( − 3 2) . Then t is a real number with csc(t) =− 3 2 . Since csc(t) < 0, we have that π
