[QUOTE="PsychonautQQ, post: 4529842, member: 482086"] [h2]Homework Statement [/h2] Consider the curve r = <cos(3t)e^(3t),sin(3t)e^(3t),e^(3t)> compute the arclength function s(t) with the initial point t = 0. [h2]Homework Equations[/h2] s = integral |r'(t)|dt [h2]The Attempt at a Solution[/h2] Okay so if you work all of this out it turns out it's not as bad as it looks.. it's set up to come out really nicely it appears. I end up with s = 3^(1/2)e^(3t) but my online homework program is saying that this is wrong... Do I ever use the information that the initial point is t = 0? I don't understand why they need to tell me that... [/QUOTE]
