    Parametric representation for the surface

    Find a parametric representation for the surface. Parametrize with respect to y and θ. (To enter θ, type theta.)
    The part of the cylinder  x^2 + z^2 = 1 that lies between the planes y = -1 and y = 3
    x = sin(θ)
    y =
    z =
    where\ 0 \leq theta  \leq \pi

    These are the standard cylindrical coordinates.

    This is correct, but a brief explanation would be appreciated, or a helpful link.
