         cos(θ) = ³/₅ cos⁻¹[cos(θ)] = cos⁻¹(³/₅)                  θ ≈ 53.13       sin(θ) > 0 sin(53.13) > 0           0.8 > 0 1. tan(θ)    tan(53.13)    1¹/₃ The answer is A. 2. sec(θ)     sec(53.13)     1²/₃ The answer is A. 3. cot(θ)     cot(53.13)    ³/₄ The answer is B. 4. csc(θ)     csc(53.13)     1¹/₄ The answer is C.
