Answer: In Exercises 7378, find the vectors T and N, and the unit binormal vector for
Chapter 12, Problem 77(choose chapter or problem)
In Exercises 73–78, find the vectors T and N, and the unit binormal vector for the vector-valued function r(t) at the given value of t.
\(\mathbf{r}(t)=4 \sin t \mathbf{i}+4 \cos t \mathbf{j}+2 t \mathbf{k}\) \(t_{0}=\frac{\pi}{3}\)
Text Transcription:
r(t)=4 sin t i+4 cos t j+2 t k
t_0= pi/3
B=T times N
