In abstract algebra, a normal subgroup is a subgroup which is invariant under conjugation by members of the group of which it is a part. In other words, a subgroup H of a group G is normal in G if and only if gH = Hg for all g in G, i.e., the sets of left and right cosets coincide.Normal subgroups (and only normal subgroups) can be used to construct quotient groups from a given group.n other words, a subgroup H of a group G is normal in G if and only if gH = Hg for all g in G, i.e., the sets of left and right cosets coincide.
Therefore is orthogonal to. The definition of the unit normal then falls directly from this. Because is a unit vector we know that for all t and hence by the Fact is orthogonal to. However, because is tangent to the curve, must be orthogonal, or normal, to the curve as well and so be a normal vector for the curve.All we need to do then is divide by to arrive at a unit normal vector.ext 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.
