Consider the curve with parametrization given by: r ( t ) = ( 2 2t 12+1 - 1 , 1+1 where this curve begins at the point (1,0) and continues as t increases from t=0. . Now re-parametrization curve by arc length. . Simplify your work as much as you can. If you do this correctly, you'll get a familiar curve. . Find the curvature of this curve as a function of the arc length s
