Takehome Problem.
Note that you
must clearly and completely show all your work in order to get full
credit.
1.
Show that the following curve is a unit
speed curve and compute T, N, B.
2.
It can be shown that since the curve in 1. is a unit speed curve, its
curvature function
and torsion function
are defined by the
equations below. Use your results in 1.
to find these two functions. (Note that these are just standard 1-D
functions defined on the reals.)
3.
Give an example of a unit speed curve that
has both nonzero constant curvature and nonzero constant torsion, and
show that this is the case.
