2. ### Prove that if a vector valued function r(t) has a constant length then r(t) and r0(t) are orthogonal.?

|r(t)| = constant implies that 1. r(t) either doesn't change with t, r'(t)=0 or 2. its...would change also by the triangle inequality. In either case since 1. r'(t)=0 or 2. r(t) dot r'(t) = r(t)r'(t)cos(90) = 0...
