1. The problem statement, all variables and given/known data Consider the curve r = (e^−2 t cos(3 t), e^−2 t sin(3 t), e^−2 t) . Compute the arclength function s(t) : (with initial point t=0 ). 3. The attempt at a solution r'(t) = <-2e^-2t*cos(3t) + e^-2t*-3sin(3t), -2e^-2t*sin(3t) + e^-2t*cos(3t), -2e^-2t> Then what, do I find the length of that derivative? Then take the integral of 0 to t? I dunno.
