I have a question about reparameterizing curves. My specific question is "Reparameterize the curve with respect to the arc length measured from the point where t=0 in the direction of increasing t. r(t)=e^t*sint i +e^t*cost j"(adsbygoogle = window.adsbygoogle || []).push({});

I understand the whole process about finding the answer, but I have one important problem, when they give you a point "t=0" does that point plug into the derivative of r(t) and you solve for |r(t)| from there? And if I replace that t=0 with a point (1,1) or something, how do I go about dealing with that?

Thanks!
