Can someone help me get started on this question? I need to show that the magnitude of \(\displaystyle \vec B'\) is equal to the absolute value of the torsion of a curve. I think I may need to start with \(\displaystyle \vec T\) and \(\displaystyle \vec N\), but I am not sure how to get started. One hint I have been given is that a positive value of torsion corresponds to the curve twisting towards \(\displaystyle \vec N\). If I've made part of my question unclear please tell me! Any help would be great.
