a curve is given as 3 parameters of t:(adsbygoogle = window.adsbygoogle || []).push({});

x=a(3t - t^3), y=3a(t^2), z=a(3t + t^3)

i have to find the arc length measured from origin and curvature as functions of t.

would i be correct in using the integral at the bottom of page 2 here: http://homepages.ius.edu/wclang/m311/fall2005/notes17.2.pdf
