Find the arc length parameterization of r(t) = <(e^t)sin(t),(e^t)cos(t),10e^t>
The Attempt at a Solution
so I guess i'll start by taking the derivative of r(t)...
r'(t) = <e^t*cos(t) + e^t*sin(t), -e^t*sin(t) + e^t*cos(t), 10e^t>
now do I do
ds = |r'(t)|dt
and integrate? what then? I don't really understand the question or what I'm trying to do really...
