Homework Statement
verify that |T ' (s)| = |T ' (t)| / |r ' (t)|
Homework Equations
K = |dT / ds|
K = |r'(t) x r''(t)| / |r'(t)|^3 the x is a cross product
The Attempt at a Solution
I don't know how to start this problem because one side of the verification is in terms of arc length and the other side is in terms of time. Could some one help me get the ball rolling and explain how I get both sides in terms of the same parameter
