(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Identify the following surfaces:

i)r.u=L

ii)r.u=mlrl for -1[itex]\leq[/itex]m[itex]\leq[/itex]1

where k, L, m are fixed scalars and u is a fixed unit vector.

2. Relevant equations

3. The attempt at a solution

The first one is in the same form as the equation of a plane, but u is not necessarily the normal, so I'm confused. For the second one, I have no idea.
