dear all, how could I find the curve satisfying
$\displaystyle \tau=c \kappa$where $\displaystyle c$ is a constant, $\displaystyle \kappa>0$?
Here $\displaystyle \tau$ is torsion, $\displaystyle \kappa$ is the curvature.
Also, I do not know what really this problem means. Is the curvature being constant?
