NAME:
1. [5] TRUE/FALSE: Circle T in each of the following cases if the statement is always
true. Otherwise, circle F. Let θbe a real number and kand integer.
T F cot θis the slope of the terminal side of θ
T F The domain of tan−1θis [−1,1]
T F cot(−θ) = −cot θ
T F The sec function is an even function.
T F The range of cos−1is [0, π]
T F The range of cos θis [0, π]
T F csc 2θ=1
2 sin θcos θ
T F cos(θ+ 3θ) = cos θ+ cos 3θ
T F cos(θ+ 3θ) = cos θcos 3θ−sin θsin 3θ
T F ln e0= 0
