  1. sin(θ) = -1
    sin⁻¹(sin(θ)) = sin⁻¹(-1)
                    θ = -90
    sec(θ) = sec(-90) = undefined number

    2.       csc(θ) = 1
    csc⁻¹(csc(θ)) = csc⁻¹(1)
                     θ ≈ 57.3
    cos(θ) = cos(57.3) ≈ 0.54

    3.      sin(θ) = -1
    sin⁻¹(sin(θ)) = sin⁻¹(-1)
                    θ = -90
    cot(θ) = cot(-90) = undefined number

    4.      sin(θ) = -1
    sin⁻¹(sin(θ)) = sin⁻¹(-1)
                    θ = -90
    cos(    θ) = cos(-90) = 0

    5.      sin(θ) = -1
    sin⁻¹(sin(θ)) = sin⁻¹(-1)
                    θ = -90
    csc(    θ) = csc(-90) = -1
