## Main Question or Discussion Point

How can I show that the binormal vector is orthogonal to the tangent and normal vector. I know i should use the dot product to determine this, however i do i actually go about doing it?

I.e it equals the determinant of the vectors (in rows) a,b and c.

Isn't that (most of) theHow can I show that the binormal vector is orthogonal to the tangent and normal vector.

Maybe you're using a different exposition than I would expect -- what definition of "binormal vector" is your class using?
