I need to find the natural equations for the equations given

1. Find the natural equations (s) for the curves below. Remember that you computed their natural parameters and curvatures in Curvature HW. - Catenary r(t)=tx+coshty - Logarithmic spiral r(t)=etcostx+etsinty - Tractrix r(t)=(cost+lntan2t)x+sinty 1.
