Im trying to understand the steps to finding a point on the surface where the tangent plane is perpendicular to following tangent plane

The plane has normal vector . Find points on the surface at which the gradient is parallel to that vector.
on the surface of which vector?

If your surface is given by f(x, y, z)= constant, then is perpendicular to the surface. That vector must be parallel (so a multiple of) <1, 1, 1>. Now, what surface are you talking about?
