    Thumbs down Cotangent pi/2

    I know that

    Tan(0) = 0
    Tan(pi/4) = 1
    tan(pi/2) = undefined

    Cot(0) = 1/0 = undefined
    Cot(pi/4) = 1/1 = 1


    Cot(pi/2) = This is the one I am stuck at.
    Since it equals 1/undefined. What happens?

    \cot\frac{\pi}{2}=\frac{\cos\frac{\pi}{2}}{\sin\fr  ac{\pi}{2}}=\frac{0}{1}=0
