    How to do this question?

    Find equations of
    1. the tangent plane and,
    2. the normal line to the surface represented by the equation:
    yz = ln(x+z)
    at the point (0,0,1).

    Thanks

    If F = yz - \ln \left( {x + z} \right) then the vector you need is \nabla F\left( {0,0,1} \right).
