Exercise 7
Exercise 7. Show that the curvature of a circle of radius r is , and the
curvature of the line is zero (First you need to find arclength parametrizations
for these curves).
Recall that, as we showed earlier, there exists a unique way to reparametrize
a curve a: [a, b] – R" by arclength (given by a o s-(t)). Thus the curva-
ture does not depend on parametrizations. This together with the following
exercise shows that k is indeed a 'geometric quantity'.
