Calculus 3: How to reparametrize a vector function (with respect to arc length)

This calculus tutorial covers how to reparametrize a vector function r(t)=(2/(t^2+1)-1)i+2t/(t^2+1)j with respect to the arc length starting at (1,0) to t. This question is from the Multivariable Calculus textbook by James Stewart, 9th ed.
