  1. cos x - 1 / 2 x

    can't lies in the third quadrant.

    Go on:

    wolframalpha . c o m

    an type cos x - 1 / 2 x

    you will see graph

  2. maybe you mean cos x = -1/2
    Since cosθ = x/r, and θ is in QIII
    y = -√3

    sinθ = y/r = -√3/2
    tanθ = y/x = √3
    cotθ = x/y = 1/√3
    secθ = r/x = -2
    cscθ = r/y = -2/√3
