  1. cot(θ) = 9
    or
    tan(θ) = 1/9
    recall that tan θ = opposite/adjacent
    so draw a right-angled triangle with opposite 1 and adjacent 9
    find the hypotenuse h
    h^2 = 1^2 + 9^2 = 82
    h = √82

    sin θ = 1/√82 , cscθ = √82
    cosθ = 9/√82 , secθ = √82/9
    tanθ = 1/9 , cotθ = 9
