Next we need to talk about the unit normal and the binormal vectors. The unit normal vector is defined to be, The unit normal is orthogonal (or normal, or perpendicular) to the unit tangent vector and hence to the curve as well.Weâve already seen normal vectors when we were dealing with Equations of Planes. They will show up with some regularity in several Calculus III topics.ext we need to talk about the unit normal and the binormal vectors.
