(adsbygoogle = window.adsbygoogle || []).push({}); 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.
