Finding unit tangent, normal, and binormal vectors for a given r(t) This produces the same answers I ended up with before (which is good!), and is much, much cleaner. Thanks very much! |

Finding unit tangent, normal, and binormal vectors for a given r(t) I'll keep that in mind! You've already helped a lot, but my remaining question, then, I suppose, is concerning N(t): simply taking bigN=D[bigT,t]/Norm[D[bigT,t]] outputs a massive jumble of fractions and roots interspersed with Abs values. Replacing t->1 and passing it through FullSimplify gives a reasonable seeming answer, but I don't have any way of knowing if I can trust it. The same goes for B(t), except that it of course is Cross[bigT,bigN]. Thanks much again, either way! |
